Subject Description

The objectives are to understand the fundamental concepts of momentum, heat and mass transfer and to be able to apply this knowledge to the solution of problems in process engineering. Contents: (a) Momentum transport: Newton's law of viscosity, viscosity of gases and liquids, shear stress and momentum flux, shell balances in laminar flow. Boundary layer theory. (b) Heat Transport: Conduction; Fourier's law; thermal conductivities of gases, liquids and solids. Steady state conduction through planar and cylindrical resistances, shell thermal energy balances, conduction with a heat source. Calculation of temperature profiles in conductors. Laplace and diffusion equations. Solution techniques. Convection; definition and evaluation of heat transfer coefficient, overall heat transfer coefficients; combined conduction and convection. (c) Mass transport: Molecular diffusion, eddy diffusion, bulk flow. Fick's first law, definition and use of driving forces (mass, molar, volume etc.), average velocities and fluxes. Diffusivities of gases and liquids. Application to binary mixtures. Equimolal counter diffusion and stationary component diffusion.
