两种湍流模型在潮流能水轮机数值模拟中的适用性研究
The Study on the Applicability of Two Turbulence Models in the Tidal Turbine
摘要
Abstract
During the simulation towards horizontal axis tidal current energy turbine under the specific turbulent conditions ,different turbulence models for calculation result has a certain impact .T o choose suitable turbulence model for the description of the designed turbine’ three‐dimensional flow field ,SS T k‐and Realizable k‐ε were adopted to perform simulation ,gaining the performance parameter of the tur‐bine ,flow velocity at the position of 1?5D af ter the turbine and turbulence intensity distribution .A model turbine was tested in flume .Comparison between the testing results and the simulation results w ith the tw o different turbulence models revealed that the simulation w ith SS T k‐turbulence model is more accurate than that w ith Realizable k‐ε turbulence model at the low tip speed ratio ,the simulation w ith Realizable k‐εturbulence model is more accurate than that w ith SS T k‐turbulence model at the high tip speed ratio .T he velocity distribution gained by numerical simulation w ith different turbulence mod‐els is similar ,but for the prediction of turbulence intensity ,SS T k‐has more advantages .Considering the practical operating conditions of the turbine ,SS T k‐turbulence model is more rational .关键词
