Thank you! I found this example (slit), but I was not sure if it is a right approximation. But I guess it is the best that I can get- I went on to research on actual velocity profile in the entry stages of flow in a pipe (so 3D), and it turns out that it cannot be described by a single...

Chestermiller I actually made a mistake saying that the equation concerns flow between plates- it is flow over a plate. I don't know what is the one for the parallel plates- do you know it? do you think it could be used here? The radius of the pipe is about 10x of the BL thickness. Thanks again

Dear Chestermiller Thank you, but I am afraid that my problem tackles pipe with quite small radius. The thing is I need analytical check for CFD simulation, that cannot rely on such a coarse assumption. Also the function is far from being linear- for the entrance of the pipe that would vitally...

Hi I cannot find an equation for a boundary layer in a pipe flow (laminar). I am looking for an equivalent of the equation δ(x)=4.91x/(√Re) that works for a flow between plates (x is the distance downstream). The thing is- I am looking for BL thickness for still undeveloped flow. I would be...

BOUNDARY CONDITION PROBLEM I have came up with matrix for numerical solution for a problem where chemical is introduced to channel domain, concentration equation: δc/δt=D*((δ^2c)/(δx^2))-kc assuming boundary conditions for c(x,t) as : c(0,t)=1, c(a,t)=0. Where a is channel's length...
