About streamline-fish oscillate propulsion Analysis
i doing streamline-fish oscillate propulsion Analysis! (2D)
First: i use NACA0012 as fish then use gambit draw grid amd mesh
second:write c++ control fish fin oscillate (flexible fin) in UDF
third:in Fluent(12.0) to simulation! run!! until 50s become steady
and next step is take control volume calculate momentum equation!
now my problem is my efficency very high (30~50%) and drag coefficient curve i can't understand and vortex (have two vortex combine one vortex) in Fe=1.0
have any references about fin oscillate propulsion,efficency,drag coefficent and other anaysis?
