| Main themes |
The teaching alternates academic courses and exercices in small groups so as to face the student with direct application of the subjects.
The courses includes the following chapters: Kinematic of fluids - mass conservation - law of momentum - Kinetic and Mecanical energies - Conservation of energy - Closure of the set of equations - Viscosity - Navier-Stokes equation - Laminar flows - boundary layer - Turbulence - Friction factor - Head losses - Pumps - Measurement of pressure and flow - Heat transfer by conduction - Forced convection, natural convection - Dimensional analysis - Unsteady conduction - Heat exchangers - Radiation - Boiling, condensation - Humid air - Molecular diffusion in simple binary systems - Mass transfer coefficient.

| Aims |
To understand the laws of conservation of mass , quantity of momentum and energy and their mathematical formulations (local formulation, 1D formulation, steady state, ...); knowledge of closure laws (viscosity, heat conduction, diffusion coefficient); ability to solve classical flow and heat transfer problems; familiarisation with orders of magnitude, associated technologies (pumps, heat exchangers, ...) et measuring instruments (Pitot tube, flow measurements, psychrometer, ...); ability to tackle various applications through a basic knowledge of the modeling of conduction phenomena, convection, radiation, turbulence, diffusion, vaporisation. This teaching should serve as a basis for several courses oriented towards technical aspects of the applications to bio-engineering and environmental protection.

| Content |
The course contents include the following chapters: kinematics; conservation of mass; law of momentum; Bernoulli equation and mechanical energy balance equation; conservation of energy; viscosity; Navier-Stokes equation; laminar flows: plane surface, cylindrical tube, flow between two rotating cylinders; dimensional analysis and similitude; flow around a small sphere; notion of boundary layer; notions of turbulent flows; friction factors; calculation of head losses; choked flow; measuring techniques of pressure and flow rate; conduction heat transfer: plane wall, cylindrical wall, electrical cable, chemical reactor; forced and natural convenction; transient heat conduction; convection coefficient; heat exchangers; diffusion; Fick's law for a binary mixture; humid air; priciples of air conditioning. The course includes a set of exercise sessions where the student is got used to the concepts and to the orders of magnitude.
