| Abstract: | Mathematical models of propellers were created that investigate the influence of periodic boundary conditions on predictions
of a propeller’s performance. Thrust and torque coefficients corresponding to different advance coefficients of DTMB 4119,
4382, and 4384 propellers were calculated. The pressure coefficient distribution of the DTMB 4119 propeller at different sections
was also physically tested. Comparisons indicated good agreement between the results of experiments and the simulation. It
showed that the periodic boundary condition can be used to rationally predict the open water performance of a propeller. By
analyzing the three established modes for the computation, it was shown that using the spline curve method to divide the grids
can meet the calculation’s demands for precision better than using the rake cutting method. |
