Question

Answer with either yes or no and explain breifly your answer. Momentum Transport Laminar flow is a subset of potential flow? Turbulent flow is very orderly and not chaotic Whcrc potcrntal ow i sae o wal a boundary layar foms When a boundary layer forms it begins laminar All boundary layer flow is turbulent When pipe flow is fully develop the entire cross section is in the boundary layer Time smoothing of vz' is always zero . . Reynolds stresses represent additional momentum transport associated with turbulent fluctuations Approximation of the Reynolds stresses is a trivial part of analyzing turbulent flow

Explanation / Answer

Laminar flow is subset of potenitial flow: No

Potential flow is irrotational flow. Irrotational flows are often characterized by negligible viscosity effects. Viscous effects become negligible, for flows at high Reynolds number that are dominated by convective transport of momentum.

Turbulent is very orderly not chaotic: NO

Basic Def of Tubulent flow is flow regime with charecterized by chaotic changes in pressure and flow velocity. The stream lines of turbulent flow is not in order.

Where potential flow is exposed to wall, a boundary layer forms: No

The potential flow over bodies are invicid and irrotional, beacuse viscous effects are resposible for boundary layer formation.

When a boundary layer forms it begins laminar: Yes

Due to the flow is viscous which creates boundary layer over surface of extrenal body and flow starts as viscous flow which means laminar flow.
