一种舰船流场特性计算方法研究
A Method of Ship Flow Field Numerical Calculation
摘要
Abstract
The influence of grid division and turbulent model to resistance ,wave ship and precision of flow prediction has been investigated by selecting ship model DTMB5415 as calculated object and using RANS method and VOF model . First ,coarseness ,middle and huge grid division have been designed to calculate wave flow field .By comparing resistance and wave ship date of the test with calculating data ,the results show that middle count grid divisions can obtain veracity of calcu‐late results and higher calculate efficiency .Second ,three turbulent flow models have been used to compute total resistance and ship wave .The SST k‐ω turbulent flow model can satisfy calculated results accuracy under high calculate rate .Finally , middle grid division and SST k‐ω turbulent flow model have been selected to calculated ship wave .The results showed that the calculated results have been agreed with the experiment data .关键词
