Goals

The module is about energy exchanges and transformations dealing with moving fluid. The question is approached by a global problematic where the stress is put on thermodynamics and transformation process (combustion turbomachines, combustion rotating machines and steam engine, gasification processes) and by a local approach where the thermal exchanges are considered. The objective is to precise the basic concepts that allow a calculation and a sizing of the energy system (aerospace propulsion, energy production) but also identifying the limits of their possible optimization. Lectures provided by industrialists complete the basic teachings (thermal exchangers).

Content

Convective and radiative heat transfer :
Phenomenology, heat transfer modes, thermal resistances and their limits, radiation with or without participating media, natural and forced convection for internal / external flows, laminar or turbulent.
Radiometry / black body: radiometric quantities, radiative equilibrium and black body, Planck law.
Surface radiation: phenomenology, grey/lambertian surfaces, Snell's law, real surfaces, view factors
Participating media: radiative transfer equation, emission / absorption in gases,diffusion (Rayleigh/Mie)
Convection equations, models with turbulent viscosity, incompressible flows, Boussinesq approximation, boundary layer approximations.
Scale analysis, application to those equations, dimensionless numbers and their use in transfer laws
Flat plate boundary layer, scale analysis, profiles (Blasius, log.law), transfer laws
Natural convection on a wall: scale analysis, transfer laws, case of horizontal walls
Forced convection in ducts: mixing temperature, entry length, fully developed flow, developed thermal solution for constant flux or temperature. Profiles and transfer in developed conditions.
Natural convection phenomena in internal flows: thermosyphons, cavities, stratification, instability.

Thermodynamics:

This part of the course is divided into two sub-parts:
- 4h of lecture on the basics of thermodynamics (expected to have been studied during the previous years) and on turbo-reactors thermodynamics (new topic).
- a 12h project. Students will work within groups (with around 8 students per project). The aim is to improve your knowledge about thermodynamic machines by studying carefully one of them. You will be invited to design the machine on a thermodynamic point of view (gas turbine, diesel engine, turbo-reactor...) considering the constraints due to its application (weight, size, efficiency, etc...). Several topics will be available so that students from different backgrounds can work on topics interesting to them.
