CHE312A - Heat Transfer & Its Applications

Introduction to heat transfer, scope, variables and general applications Modes of heat transfer (conduction, radiation, convection); Heat conduction: Fourier law, thermal conductivity in gases, liquids and solids and their estimations. Radiation: thermal radiation, radiation properties, view factors, Heat exchange between surfaces: General differential energy balance equation, dimensionless form, simplified forms, boundary conditions, similarity and scaling analyses. Steady state conduction in stagnant fluids and solids, fins, definition of heat transfer coefficients. Unsteady heat conduction in stagnant fluids and solids. Heisler charts, 2numerical solutions and Mat lab, etc. Convective heat transfer (laminar): heat transfer in ducts, flat plate, 3falling film, natural convection, correlations. Convective heat transfer (turbulent): heat.
