[imipramine]

hi, I'm trying to model mixed convection in a lid-driven Isosceles triangular cavity, boundary conditions are :
left inclined wall: sinusoidal temperature profile (min=290K , max=310K)
right inclined wall: constant temperature at 290K
bottom wall: constant temperature at 310K driven by x-direction velocity of
0.1m/s .

dimension of triangle are :
base = 96mm
hight = 24mm

the question is: which solution method (pressure velocity coupling and spatial descritization) is appropriate for this problem . I can't lead this convection problem to convergence.

can you guys write some suggestions for me ?

thanks
