Description |
This course gives an introduction to general fluid mechanics, to mass and heat transfer and reactions. The first part deals with the concept of continuous medium, static and kinematic of fluids, integral forms of the fundamental balance equations (conservation of mass, momentum and energy), theorems of Bernoulli and applications (velocity and flow measurements, head losses,...), momentum theorem, Navier-Stokes equations and main exact solutions (Couette and Poiseuille), boundary layer, Dimensionless numbers (Reynolds, Prandtl, Sherwood, Nusselt, ...) and notions of turbulence (2D and 3D). The second is dedicated to Notion of intensive / extensive property, convection-advection and diffusion, Basis in Mass transfer (Fick's law, notion of mass transfer coefficient). Basis in Heat transfer: conduction (Fourier's laws), convection, radiation. Notion of heat transfer coefficient. Analogies between momentum, mass and heat transfers. Estimation of diffusion coefficients. Reaction kinetics in homogeneous systems: reaction rate law, reaction order, kinetic constant, Arrhenius law. Application of mass transport equation to various systems : -Notion of homogeneous and heterogeneous systems; steady state / unsteady state systems; open and closed systems -Global mass balances without and with reaction, notion of conversion rate and generalized extent of a reaction. Application to simple and complex reactional systems -Detailed mass balances at the macroscopic scale of a single-phase chemical reactor, notions of uniformity. Application of balances in perfectly stirred and in plug flow reactors. -Non ideal reactors. Systemic approach : Residence Time Distribution |
