Abstract
This paper presents the theoretical model and numerical methods which are applied in computer program SOLAGA for computations of viscous flow around ship propeller as well as for modelling of cavitation phenomenon. The model presented in the article is based on mass conservation equation and Reynolds averaged Navier-Stokes equation, the turbulent viscosity is approximated with the use of Spalart-Allmaras turbulent model. The numerical model used for solving the system of main equations is based on Finite Volume Method. The procedures for cavitation predictions applied in the SOLAGA program are based on travelling bubble model. This paper presents the results of computations of KT, KQ characteristics for conventional and skewed propeller. The results are compared with the data obtained from experiment. The results of computation of cavitation for the skewed propeller are presented as well.
