hello to you,
i am modeling a hydro cyclone, under this circumstances: velocity: 14.7m/s transient solver oil and water misture>> Vfoil=0.05 Eulerian setup RMS setup Pi=400kpascal simple method first order (for first evaluation) considering the courant number>> the time step is about 0.0001 iterations>> 50000 however since i dont have access to a versatile pc, i keep the time step=0.01 lastly, after 2 or 3 thousand iterations, the continuity residual keeps rising in a way that it reaches 1e8 at iteration=5000. any help to overcome this obstacle is highly appreciated. m.zandie@ut.ac.ir tell:+989187833918 |
