Default kinetic theory of granular flow problem
Posts: n/a
hello everbody

i am modelling a solid-liquid flow in fluidized bed using kinetic theroy of granular flow for solid phase describing . I define algebaric equilibrium model for granular temperature and also defined square of mean velocity for the max granular temperature.

when i was checking solid granular temperatre in cfx post and am geting value in the the range of 1e+20. this is not expected value, after some iterations the linear solver ends with fatal overflow.

if i include the zero equation model for granular temperature , i never getting this kind of higher value what is wrong in granular temperature model

what is solution for this problem

with regrads user

Regards, cfd user
