linear inlet velocity profile
Hi guys,
i want to create a linear velocity profile at the inlet patch for simulating couette flow in a channel with less computational effort, therefore I tried following code: Quote:

any idea? my results are not right, so there must be a mistake

Hi,
in general I will produce a linear gradient velocity profile at my inlet in y-direction This is my test setup http://upload.wikimedia.org/wikipedi...inar_shear.svg 1. I tried by groovyBC but I failed - 2. I changed the hard coded parabolicVelocity.C File of HJasak and got the profile at figure 1. - it seems to be right BUT if i calculate further I got wiggles at the corner on bottom. How can I avoid them?(see Figure 2 & Figure 3) and in Couette there should be no velocity gradient in y-direction, but there is! and in general, how can I set this profile to whole domain and not just to the inlet? Here is my Member Function of the linear velocity profile: Code:
void linearVelocityFvPatchVectorField::updateCoeffs() |
Greetings to all!
