Dear all !
I want to calculate pressure drop in poiseuille2d, after running Pressure Drop is about .0006 in lattice units.
Other data :
u=0.02
Re=10
N=50
dx=0.02
dt=0.0004
Omega = 1.25
Nu_LB = (1/Omega - 1/2) / 3 = 0.1
Nu_p = Nu_LB* dx^2 / dt = 2.5 (m^2/sec?)
Deltap_P = Deltap_LBdx^2/dt^2Phrp_p
What is Phro_P (in default system)?
cheers
I try to use this program to simulation of water (nu_p=1.005*10^-6), I think Omega(Nu_LB)is constant in program, but when I calculate dt,dt, based on Nu_LB=.1, (Omega = 1.25) and change N to 1000 and u to .01, in results I see:
Iteration 500 565960.1803; rho=6.4684491e+244; uMax= 1.0000233;omega = 0.28571429
rho=6.4684491e+244 and omega = 0.28571429 ??///
Why?
can any one help me?
How can I control Omega in Program?
