Hi users. Can you help me, what's kind of parameters i must turn on for modelling water flow in vertical channel with zero speed? The water must flow down on the wall, with influence of gravity only. I turned on the gravity, VoF model, k-epsilon model, added 2 phases (air primary, water secondary), but on the end of modelling, water doesn't flow. I modelled flow with velocity 0.5 m/s, there all is ok. Who worked with gidraulic flow, please hint me. Thanks. I attached the pictures of channel with water velocity 0.5m/s. If you need something else - tell me.
