| Shrnutí: | Numerical study is presented in this work for turbulent cavitating flow pattern
simulation on a hydrofoil, using state equation of cavitation model along with
combined turbulence model for mixed fluid based on commercial software
FLUENT 6.0. This solver is based on finite volume method. Cavitating study
yield irregular behavior with the variation of cavitation values (𝜎� This study is
focused on pressure variation, vapor volume fraction, lift and drag forces on the
foil section for various cavitation values at 7° angle of attack. Cavitation
initiation begins at the foremost surface and covers towards the end chord with
reducing cavitation value. Moreover, the change of vapor region pattern is
predicted towards the front of the foil. Finally, transitional flow range is
observed for � 𝜎lues 0.8 to 1.2 with large standard deviation. |
