How to get a velocity profile using UDF?
I tend to get a velocity profile on the wall(like airfoil or car) using UDF.but I find it's hard to search the adjacent point for a given point,if anybody kown about this area,please help.

Re: what is displacement thickness in boundary lay
The defination of displacement thickness is :because the existence of boundary layer make the free stream-line "Off" the wall. the distance between the wall and the free stream-line called "displacement thickness "
How do you know I know?:) |
Re: what is displacement thickness in boundary lay
you can calculate the displacement thickness as follow: delta_star=integral from 0 to h (1-desity*u/desity_far*u_far)dy
you can let h equal to delta. |
Re: what is displacement thickness in boundary lay
The defination of momentum thickness is :because the existence of boundary layer make the loss of momentum rate.
momentum thickness :theta=integral from 0 to h ((desity*u)/(desity_far*u_far)*(1-u/u_far))dy |
