The module is about energy exchanges and transformations dealing with moving fluids. The question is dealt as well from a local phenomenon point of view with an emphasize on radiative and convective heat transfers as from a system point of view where energy transformation is approached from a thermodynamic point of view (improvements and optimization of jet engines, turboshafts and reciprocating engines). Theoretical teachings are completed with group projects including dedicated lab sessions (chosen among boiling heat transfer, air conditioning or combined heat and power generation).
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:
- 16h of lecture on the basics of thermodynamics (expected to have been studied during the previous years), on turbo-reactors thermodynamics (new topic) and on the improvement of the thermodynamic cycles of gas turbines and reciprocating engines.
- A visit (2h) of a building at the Versoud airfield, near Grenoble, where aircraft and helicopter engines are stored for teaching purposes.
