Hi everyone,
I am new to COMSOL. I am trying to simulate a plane Poiseuille flow between 2 flat plates with a gap of 0.05 m and a pressure difference of 0.1 Pa over 0.1 m length (giving dP/dx=-1 Pa/m). The fluid is water- dynamic viscosity is 8.9*10^(-4) Pa s.
So, according to ocw.mit.edu/courses/mechanical.../MIT2_25F13_Couet_and_Pois.pdf
my maximum velocity should be 0.35 m/s but according to the simulation file I have attached, I am getting
something close to 0.2 m/s.
Could you please tell me what I am doing wrong?
Best Regards
Anindita
