Equipping practicing engineers and students with the tools to independently assess and understand complex material on the topic, this text is an ideal precursor to advanced heat transfer courses. Intermediate Heat Transfer discusses numerical analysis in conduction and convection, temperature-dependent thermal conductivity, conduction through a slab from one fluid to another fluid, steady-state heat conduction in a two-dimensional fin, and truncation and round-off errors in finite difference method. Replete with sample problems to clarify concepts, this is an indispensable resource for professionals and seniors and first-year graduate students pursuing tracks in mechanical, aerospace, nuclear, and chemical engineering.
