Numerical simulation of cavitating flows around an oscillating circular cylinder

초록/요약 도움말

Cavitating flows around an oscillating circular cylinder are numerically investigated by developing an efficient numerical method which combines a homogeneous mixture model with the effect of vapor generation, a semi-implicit pressure correction method for compressible two-phase flows, and an immersed boundary method to apply specified velocity conditions to a moving solid surface. The numerical results for cavitating flows around a stationary cylinder and non-cavitating flows around an oscillating cylinder compare well with the previous works. Computations are further carried out for cavitating flows around an oscillating cylinder to investigate the combined effects of cylinder oscillation and cavitation on the flows and the resultant drag and lift coefficients.
