Course information

The main objective of the course is to familiarize the students with the principles of momentum, mass and heat transport phenomena. Topics to be covered include: ▪ Introduction to Transport phenomena. Basic concepts. Equilibrium and rate processes. Simple material and energy balances. ▪ Molecular transport mechanisms. Examples of molecular transport processes include heat conduction (energy transfer), molecular diffusion (mass transfer), and fluid flow (momentum transfer). The analogy between heat, mass and momentum transfer. Fourier, Fick and Newton Laws. The one-dimensional transport equations. Transport properties (thermal conductivity, diffusivity, viscosity). ▪ The conservation concept. Input-output balance, generation, accumulation. The general balance equation in differential form. The continuity equation. ▪ Molecular transport under steady state conditions (one direction transfer problems). Heat and mass transfer without or with a constant generation term. Momentum transfer with generation terms (fluid flow under pressure gradients and gravitational fields). Laminar flow in a tube. Laminar flow between parallel plates. Introduction to tubular flow. ▪ Transport with Net Convective Flux. Review of convection. Simple heat and mass transfer problems with convection. The Navier-Stokes equations for incompressible fluids. Mass diffusion phenomena (binary mass diffusion in gases and liquids, diffusion in solids). ▪ Integral methods of analysis. Integral mass balance, mass balance of individual species, momentum balance, energy balance. Bernoulli equation. Fluid statics (manometers). ▪ Dimensional analysis. Meaning and use of dimensionless numbers. Reynolds, Peclet, Prandtl, Schmidt, Nusselt, Sherwood numbers, etc. Rayleigh Method of Analysis.
