Heat Transfer

Description

Common Section :
The student should be able, for plan, cylindrical, and spherical systems in steady-state conditions, with or without heat generation, to: 
-Establish and solve the energy balance equations in steady-state conditions to calculate heat fluxes and characterize temperature gradients, 
-Calculate heat fluxes, thicknesses of materials composing walls, pipes, spherical tanks in steady-state conditions, 
-Calculate temperatures at interfaces.

Section GP3E:
The student should be able to:
-Explain the different heat fluxes
-Establish energy balances on reactive or non-reactive systems
-Integrate differential equations to determine temperature profiles and assess heat fluxes 
-Know how to transmit a given amount of heat between two systems
-Know how to limit heat losses through a surface
-Study cases applicable to processes.

Section GB:
The student should be able to:
-Choose a technology and configuration of heat exchanger according to its uses 
-Calculate heat exchange between fluids within a heat exchanger based on steady-state configurations 
-Calculate the efficiency of a heat exchanger based on steady-state configurations
-Size the heat exchange surface of a heat exchanger according to its steady-state configuration 
-Calculate the performance of heat exchangers based on flow rates and inlet and outlet temperatures of fluids 
-Solve, in transitional regime, the energy balance equations on a perfectly stirred tank to calculate heating and cooling times according to the implemented technologies (coil, double-wall, external heat exchanger) with or without thermal loss
