Chapter 6 - Application of ANSYS to Thermo Mechanics

Abstract

This chapter presents the application of ANSYS to heat transfer problems. One of the problems in the chapter deals with heat transfer through two walls of a furnace constructed from two materials. The inner wall is made of concrete with a thermal conductivity kc=0.01W/mK, and the outer wall is constructed from bricks with a thermal conductivity kb =0.0057W/mK. The temperature distribution within the concrete and brick walls under steady-state conditions and the heat fluxes through each wall are determined in the chapter. It is a two-dimensional problem and is modeled using graphical user interface (GUI) facilities. Depending on the nature of analysis to be attempted, an appropriate analysis type should be selected. Because the outer brick wall and the inner concrete wall are created as separate entities, it is necessary to “glue” them together so that they share lines along their common boundaries. The chapter finally presents a steady-state thermal analysis of a pipe intersection.
