Asking for help, clarification, or responding to other answers. Laminar flow is a phenomenon where air, gas, or a liquid flows in parallel layers and there is no mixing of layers. Turbulent flow, unlike laminar flow, has a chaotic and random behavior that effects multiple fluid parameters. All internal flows will have a certain entrance length and in this entrance length, the flow is laminar – exactly the opposite needed for good heat transfer. CopperKettle is correct that "laminar" flow is the technical term for the opposite of "turbulent" flow.

Given the characteristic velocity scale, U, and length scale, L, for a system, the Reynolds Antonyms for turbulent flow. In turbulent flow, on the other hand, there is an additional diffusional mechanism for transport of fluid momentum toward the boundary: exchange of macroscopic fluid eddies across the planes of mean shear parallel to the bottom tends to even out the velocity distribution by diffusion of momentum toward the bottom (Figure \(\PageIndex{3}\)). – In nonscientific terms laminar flow is "smooth," while turbulent flow is "rough." All or nearly all fluid flow displays some degree of turbulence. Antonyms for Turbulent (opposite of Turbulent). Is it allowed to refer to Artificial Neural Networks as Statistical learning? 2 words related to turbulent flow: sea, flow. It is the simplest laminar flow. Note that this turbulent drag force acts to reduce the air velocity and therefore is opposite the air flow velocity vector. Turbulent flow is chaotic, forms eddies and whirlpools and is similar to the flow of a whitewater rapid. The word also means "with graceful movement", so that helps dispel any images of turbulent water. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. With other parameters remaining the same, as the lift generated by a body increases, so does the lift-induced drag. Download Full PDF Package. I think "flowing" is actually the best word for your case. Opposite of streamline flow. Ref: Hunt iii. One word used as the opposite of turbulent, at least in reference to water, is "placid.". the capacitor or the inductor? Noun. Opposite of streamline flow. Laminar vs. turbulent flow can characterize how fluid is moving, with a laminar flow being a more smooth, orderly flow, and a turbulent flow being rough and chaotic. The velocity at a given point can change in magnitude and direction. Another difference between these two types of flows is that velocity is constant at every point in a laminar flow while the velocity changes at different instances in a turbulent flow. In turn, this will effect the fluid velocity, shear stress, pressure, and fluid temperature. one with the same velocity everywhere. In contrast for the outer turbulent layer the opposite is true. the flowing water is transparent, not white or distorted). Create a free account to download. Making statements based on opinion; back them up with references or personal experience. Vortices form in stirred fluids, and may be observed in smoke rings, whirlpools in the wake of a boat, and the winds surrounding a tropical cyclone, tornado or dust devil.. Vortices are a major component of turbulent flow. What is the opposite of Turbulent? Though a boundary layer of air "sticks" to a wing, the air overtop should be moving quickly and smoothly to reduce friction drag. P.S. In contrast to laminar flow the fluid does not flow in parallel layers, the lateral mixing is very high, and there is a disruption between the layers. In nonscientific terms, laminar flow is “smooth,” while turbulent flow is “rough.” rev 2021.5.14.39313. Streaming or running also give the impression of water that's simply running, not rushing.

English Language Learners Stack Exchange is a question and answer site for speakers of other languages learning English. Find more words! –In nonscientific terms laminar flow is "smooth," while turbulent flow is "rough." Introduction to Turbulent Flow: There are two types of flow-namely laminar flow and turbulent flow. We have tried to simplify them, to help you understand this aspect of fluid dynamics better. turbulent-flow | definition: characterized by unrest or disorder or insubordination | synonyms: riotous, disruptive, unquiet, troubled, tumultuous| antonyms: quiet, steady, patient, moral, scarce It is the opposite of turbulent flow. The turbulent drag force on the horizontal air flow within the atmospheric boundary layer can approach the size of the other terms in the horizontal equation of motion. This can exist between two fluid layers (or surfaces) or a fluid and a solid surface. (i.e. turbulent 1 agitated, blustery, boiling, choppy, confused, disordered, foaming, furious, raging, rough, tempestuous, tumultuous, unsettled, unstable 2 agitated, anarchic, boisterous, disorderly, insubordinate, lawless, mutinous, obstreperous, rebellious, refractory, riotous, rowdy, seditious, tumultuous, unbridled, undisciplined, ungovernable, unruly, uproarious, violent, wild To subscribe to this RSS feed, copy and paste this URL into your RSS reader. It only takes a minute to sign up. Turbulent flow definition is - a fluid flow in which the velocity at a given point varies erratically in magnitude and direction. We know in laminar flow, the fluid particles have an orderly motion along stream lines. Sorry was using my mobile and still am. Antonyms for Turbulent (opposite of Turbulent). I think you could use the word, 'Trickle' in this case. The essential ideas of investigations of turbulent flow in a straight rectangular duct are chronologically presented. Opposite of a smooth, streamline type of viscous flow in which the fluid behaves as a system of orderly layers, with no eddies or irregular fluctuations. Behavior of turbulent flow of superfluids is opposite that of ordinary fluids 25 July 2013, by Jennifer Chu A superfluid moves like a completely frictionless In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. A laminar flow is any non turbulent flow. How would you describe water that is flowing rapidly, but is not turbulent? I've just recalled the word unperturbed. Find more opposite words at wordhippo.com! Log in. How did the Apollo guidance computers deal with radiation? Is there a word describing the feeling when cold water is drank, similar to “spiciness”? @SoumyadeepKoley to echo Nathan, Think your turbulent water faucet vs the smooth surface of a wide, but powerful river. Find 109 ways to say TURBULENT, along with antonyms, related words, and example sentences at Thesaurus.com, the world's most trusted free thesaurus. Ref: Hunt iii. What does it mean when a court case is "dismissed"? However, if there is a constriction in an artery, if the direction in which the blood is flowing is opposite to that of the pressure exerted by the heart, or even if the path that the flowing blood has to take is around a corner or curve, the flow is no longer laminar, but instead it is turbulent. The entrance length varies with the velocity of the water entering the block, but can be up to 60 times the diameter of the channel. Laminar flow is often described as "smooth". In turbulent flow, on the other hand, there is an additional diffusional mechanism for transport of fluid momentum toward the boundary: exchange of macroscopic fluid eddies across the planes of mean shear parallel to the bottom tends to even out the velocity distribution by diffusion of momentum toward the bottom (Figure \(\PageIndex{3}\)). Antonyms for Turbulent. If you need a purely technical term, you might try looking up laminar flow. 7. Calculation of Turbulent Flow through a Channel with Two Opposite Ribbed-Walls. But it's better always to clarify the intended context, this way you would get right answers faster!

All or nearly all fluid flow displays some degree of turbulence. Is 'quartodecimo omnium sanctorum' the same as 'Nov XIV' on this Latin grave inscription? The trailing vortices in the flow-field, present in the wake of a lifting body, derive from the turbulent mixing of air from above and below the body which flows in slightly different directions as a consequence of creation of lift. Also called tortuous flow; sinuous flow; eddy flow. If you need a purely technical term, you might try looking up, @CopperKettle laminar flow is exactly what I was looking for, I'll accept the answer if you create one. Relative to HVAC systems, laminar flow provides a way to maintain the clean nature of air within a space and also prevents mixing of air, which can cause … If a flow is completely uniform (no velocity difference), turbulence does not occur. Another difference between these two types of flows is that velocity is constant at every point in a laminar flow while the velocity changes at different instances in a turbulent flow. Basics of Turbulent Flow Whether a flow is laminar or turbulent depends of the relative importance of fluid friction (viscosity) and flow inertia. The ratio of inertial to viscous forces is the Reynolds number. So, if you want a less technical answer, we could say the water is clear and flowing smoothly. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, drag force depends on velocity. Laminar flow is often described as "smooth". ... the air is accelerated in the opposite direction of gravity by buoyancy due to temperature difference. Would you help me with adjectives, alive and live? A. AbdelGawad. Why are there more research papers on Android malware than iOS malware? Most flows that we can observe in nature and in engineering are turbulent, from the smoke of an extinguished candle to the flow of blood in the left ventricle of our heart.
