  © 2012 ANSYS, Inc. November 15, 2012 1 Release 14.5   14.5 Release Introduction to ANSYS Fluent Lecture 8 Heat Transfer  © 2012 ANSYS, Inc. November 15, 2012 2 Release 14.5 Lecture Theme: Heat transfer has broad applications across all industries. All modes of heat transfer (conduction, convection  –  forced and natural, radiation, phase change) can be modeled in Fluent and solution data can be used as input for one-way thermal FSI simulations. Learning Aims: You will learn: ã How to treat conduction, convection (forced and natural) and radiation in Fluent ã How to set wall thermal boundary conditions ã How to export solution data for use in a thermal stress analysis (one-way FSI) Learning Objectives: You will be familiar with Fluent’s  heat transfer modeling capabilities and be able to set up and solve problems involving all modes of heat transfer Introduction Intro.
