耦合黏-势流数值计算的CLT桨水动力性能预报
Prediction for hydrodynamic performance of CLT propeller by coupling viscous and potential numerical calculation
摘要
Abstract
According to the special geometric forms and wake vortex characteristics of the standard contracted and loaded tip(CLT)propeller,the corresponding computational theory of panel method was revised,including parametric modeling,pre-set wake vortex model and meshing.To verify the applicability of the improved panel method for predicting the open-water performance of CLT propellers with variable endplate forms,three sets of CLT propellers were built by changing the endplate parameters,and the open-water performance were calculated by the improved panel method.Comparing the panel method's results with computational fluid dynamics(CFD)method's simulation results,the efficiency differences near the design advance speed were about 2%.Results show that this program of the panel method can quickly predict the open-water performance of CLT propellers with variable endplate parameters,and the forecast accuracy meets the engineering requirements.The forecast results can be used as reference for further optimization design and experimental design.The thrust can be increased by about 10%at most near the low advance speed when the width of the original end plate is reduced by 50%.The results of the surface pressure distribution in the design section are in good argreement with those of the CFD method.关键词
