Heat and Mass Exchange

Objectives

This course introduces the three main mechanisms of heat transfer (conduction, convection and radiation). The course focuses on basic methods to estimate heat flux and temperature magnitude in systems as well as industrial or natural. The program follows the book Fundamental of Heat and Mass Transfer, Bergman et al..

Description

1. Introduction : the three modes of heat transfer, energy balance, examples.
2. Heat conduction : steady-state conduction in 1 and 2 dimensions, transient conduction.
3. Convection : forced convection, external and internal flows, free convection, conservation equations, boundary layers and empirical method.
4. Radiation : radiation concept, black body, surface effects, radiation exchange between surfaces.
5. Experimental works : infrared thermography, heat conduction coefficient and thermal diffusivity measures.

Targeted skills

- be able to calculate a heat flux or a thermal resistance in steady-state conduction.
- Be able to use empirical correlations to calculate heat transfer coefficient for external or internal incompressible flow, or in free convection.
- Be able to address spectral and angular quantities in radiation process (intensity, emissive power, irradiation, radiosity…)
- Be able to calculate radiation exchange between diffuse grey surfaces.
