kmgraju is on a distinguished road
I am analyzing 3D flow . I would like to give the inlet velocity profile as a paraboloid as the fully developed condition. The flow is in the Z direction .
According to the theory U= (1/4 μ )*(dp/dz)*(r^2-R^2). Any one give me a suggestion about the fully developed velocity profile.How I can write the expression for velocity profile in CEL expression
maximum velocity has taken as 0.12m/s .
U = 2* Umax *(1-(r/R)^2). Is this fully developed velocity profile in 3D?
Kindly help me
