Phénomènes de transport

Transport Phenomena

An introduction to transport phenomena, course given to 3rd year students in the engineering curriculum at ESPCI Paris

This course will give the basis to answer all kinds of questions and problems ranging from : why is my coffee cold way before it is sweetened by sugar ? and : how long can I stand on top of Everest without gloves ? to : how to a design a microchip to capture biomolecules ? how many showers can I take with a 10 meter square solar heater ? what do cetaceans and solar heaters have in common ? why mixing in turbulent flows is so efficient ?

General laws for transport of heat and mass

This first document describes a general framework for the transport of heat and mass. The diffusion equations (Fourier and Fick’s laws) are extended to take into account transport by convection (here convection refers to the macroscopic motion of a fluid).

Steady state one dimensional diffusion problems

This second document shows how to solve one dimensional steady state diffusion problems, in particular with source terms. It introduces the notion of effective transfer coefficient at an interface and thermal resistance. As an example, the concepts described are used to derive the bioheat equation modeling heat transfer in living tissues.

Radiative heat transfer

This document describes the characteristics of the electromagnetic radiation emitted by a body at finite temperature. It shows how one can compute the exchange of energy by radiation between two bodies.

List of problems

This document contains the definition of the problems we have considered so far in class : mass and heat transfer in the coffee cup, water solar heater, cooling a microprocessor, bioheat equation, flux of water vapor through a porous membrane.

Combined convection and diffusion

This document analyses the interplay between convection and diffusion in situations when the Peclet number is large and when thin transport boundary layers control the flux of heat or mass.
