Heat Exchange - Thermodynamics of Machines - 3EUAETH6

Goal(s)

Heat transfer:
By the end of the heat transfer module, students should have acquired a method for estimating heat transfer by conduction and convection between several bodies at different temperatures in simple cases. Emphasis will be placed on the use of numerical methods and equivalent circuit diagrams in the case of conduction.

Application to Heat Exchangers
Heat exchangers are commonly used in practice across a wide range of applications, from domestic heating and air-conditioning systems to chemical processing and power generation in large industrial plants. In the analysis of heat exchangers, it is generally practical to work with the logarithmic mean temperature difference, which is an equivalent average temperature difference between the two fluids across the entire heat exchanger. We then discuss the efficiency method, which allows us to analyse heat exchangers when the outlet temperatures of the fluids are unknown.

Test

Session normale / First session
ET = évaluation rattrapable / ER assessment : devoir surveillé écrit de 2h / 2 hours supervised written exam
CC = évaluation non rattrapable / EN assessment : le contrôle continu est composé d'une note de BE sur la conduction de la chaleur, d'une note d'interrogation en thermodynamique des machines, et d'une note de TP en thermodynamique des machines. Continuous assessment consists of a heat conduction lab report grade, and thermodynamics quiz and a thermodynamics lab report
---------------------------------------------------------------------------
Session de rattrapage / Second session
ER : la note obtenue en session 2 remplace la note ER session normale / new examination to replace ER assessment
EN : évaluation non rattrapable / retaking EN assessment is not possible
