Default turbine compt:why can't congence???
Posts: n/a
i did some turbine computation! i chose air(idea gas) as fluid, and reference pressure=14atm;energy model----total energy;k-e model;intial condition=automatic

BC:inlet---mass rate;total tempreture=1200K; outlet----reletive pressure=-600000Pa;

it never congence,but when i turn outlet's reletive pressure to 0Pa,it congence,it that 14atm have some problem?if not,where can i modify them?

how this could happen,and what can i do? thanks in advance!!!
