Gasoline stainless steel exhaust manifold airflow performance, thermal stress, thermal mode, performance thermoplastics such as numerical analysis

As cars become a trend and lightweight supercharged engine exhaust temperature brought, stainless steel exhaust manifold has been widely used with gasoline engines. Therefore, this paper has important value engineering studies Gasoline stainless steel exhaust manifold heat load. Analysis, combined with the simulation results to optimize the structure of the exhaust manifold designed to meet product  Stainless steel needle valve  of this article for a gasoline engine airflow performance stainless steel exhaust manifold, heat stress, heat mode, the thermoplastic properties of numerical simulation. Firstly, the flow field through a mathematical model,  Valve manifold  knowledge of fluid dynamics, simulation software for the flow field in the case of the engine exhaust manifold all conditions of different cylinders turned analyzed were obtained pressure distribution and flow lines distribution.

The design check valve status and computational fluid dynamics of common software applications in non-return valve

From the study of fluid flow valve mechanism departure, using numerical simulation valve internal flow, numerical simulation results to guide the design of the valve has gradually  Stainless steel needle valve  research direction. Numerical simulation tools, one can save test resources, shorten new product development time; hand it can display is difficult to draw from the test flow characteristics in detail. In this paper,  Valve manifold  FLUENT study the internal flow check valve, mainly to do the following aspects: the design brief check valve status and computational fluid dynamics in the check valve in the common software applications. Details of the basic theory and computational fluid dynamics methods for solving algebraic equations SIMPLE calculation methods and a variety of mesh generation techniques.
