sluice gate by VOF
Hi all, i have carried out laboratory tests about a sluice gate in open channel. i want to determine upstream and downstream velocities teoretically. Sluice gate has constant gate opening not varies with time. can i solve the problem by VOF analysis? i give boundary condition: inlet(u=0.2, v=0), wall(u,v=0),sluice gate (u=v=0), i have problem outlet and upper condition. first, how i do apply outlet condition ? Entirely outlet depth at the downstream of sluice gate p=0? but i dont know the outlet depth or free surface profile? Second, upper condition p=0 entirely channel cross section? similarly i dont know the water depth downstream of sluice gate I will appreciate it very much if you could give me answers Thanks
