planing craft
 

hi i am modelling only the under water portion of planing craft. we are uding sinkage and trim values obtained from experiments. at low speed fluent is giving drag comparable with experiments. but at high speeds(5m/s) the drag values are 5 times the experimental.

what should i do to get the correct drag.

i have tried using all the turbulence models and differnt domain and also using different mesh sizes.

expecting your reply soon

thanking u
