Summary

In this course, we’ve discussed several aspects of how to perform heat transfer analysis in Mechanical. Here’s the summary for each lesson:

How to perform heat transfer analysis — Lesson 1:

• Review of three heat transfer modes: conduction, convection, and radiation and how they are considered in conduction-based heat transfer analysis
• General introduction of the setup for heat transfer analysis in Mechanical

How to define temperature-dependent convection — Lesson 2:

• Convection is treated as a boundary condition in conduction-based heat transfer analysis and is controlled by two parameters: the film coefficient and bulk temperature.
• The film coefficient is not necessarily constant. In fact, in practical applications, it is often temperature dependent. Mechanical provides different ways to define a non-constant film coefficient.

How to model thermal radiation between two surfaces — Lesson 3:

• Introduction to the mechanism of radiation and how it is considered and solved in Mechanical heat transfer analysis
• Explanation of emissivity and view factor
• How to define radiation between surfaces in Mechanical and evaluate results

How to link thermal results as an input for thermal-stress analysis - Lesson 4:

• Change in temperature produces thermal strains.
• In Mechanical, temperature results of a thermal analysis can be mapped to a structural analysis to be used as thermal loads, even for a different mesh.
• Tips can be used to make sure the mapping of temperature is accurate.
