Case Study: Thermal Fluid Analysis of a Muffler

This is an introduction to the recommended software Femap Thermal/Flow for customers who are starting thermal fluid analysis with Femap.

**Case Overview** ■Product Name: Femap Thermal, Femap Flow ■Analysis: Thermal Fluid Analysis ■Industry: Automotive Femap Thermal/Flow is software for thermal fluid analysis that operates as a Femap application. It can be used with the same operational feel as Femap. Through the combination of Femap Thermal and Femap Flow for thermal fluid analysis, we calculated the flow of exhaust gases within the muffler and the temperature distribution of the muffler due to high-temperature exhaust. By using Femap Thermal and Femap Flow simultaneously, thermal fluid analysis can be conducted. It can solve complex problems such as heat transfer at the fluid-structure interface, fluid flow, thermal conduction in structures, and consideration of radiation at the surface of structures. In this case, we conducted thermal fluid analysis focused on the muffler. We confirmed that we could obtain necessary parameters for design by determining the temperature difference of exhaust gases at the inlet and outlet, the flow of exhaust gases within the muffler, and the temperature of the surface of the muffler structure. □ For other functions and details, please refer to the catalog.
