【摘要】 Modelica技术难以仿真动态特性在空间上非定常分布的流动、传热和燃烧等复杂问题,因此提出一种基于MWorks与FLUENT的协同仿真方法,设计协同仿真的耦合方式、数据交换机制和仿真架构,利用Modelica外部函数、MWorks仿真用户接口和FLUENT UDF编写协同仿真程序.以某单向阀为研究对象对此协同仿真方法的有效性进行验证.所提出的方法可实现Modelica技术与CFD技术的优势互补,能够为多领域系统仿真提供新的解决方法.更多还原

【Abstract】 Modelica can hardly simulate the complex issues such as fluid flow, heat transfer,combustion,etc.,in which the system behaviors are distributed in space unsteadily. To solve the problem,a method of co-simulation between MWorks and FLUENT is proposed. The coupling mode,data exchange scheme and simulation architecture are designed for co-simulation. The co-simulation program is implemented using Modelica external function, MWorks simulation user interfaces and FLUENT UDF. The co-simulation method is verified by a simulation example of check valve. The complementary advantages of Modelica and CFD technique are implemented by the method,which is a new method for multi-domain system simulation.更多还原
