Hi ;
ı am trying to create a model with using an empty channel and an inlet (water hydrograph). Problem is that ; - ı must create an inlet that consist of air and water ( two phases) however, water height has to be changed with time respect to mass flow. I used "open channel" mass flow inlet and pressure outlet. photos are below. channel inlet cross section : 0.7 m x 0.7 m inlet mass flow : 14 l/s calculated water velocity (in experiment): 0.181 m/s (fluent gives me 0.026 m/s because it distributes all vel at inlet cross sec (0.7x0.7) automatically. for inlet ; between time =0 second, t=360 discharge=14 l/s between t=360, t= 690 d=0.14444(x-360)+14 between t=690, t=1020 d=61.67-0.14444(x-690) between t=1020, t=1320 d=14 Best regards. thanx. |
