Lecture
This lecture covers transient heat transfer with spatial effects, focusing on topics such as lumped capacitance model, generalized solutions for different geometries, and periodic heating. The instructor explains the concepts of Bi number, Fourier number, and convective cooling in the context of solving transient heat conduction problems. The lecture also discusses the non-linear temperature distribution within a wall during transient heat conduction. Practical examples are provided to illustrate the application of these concepts in evaluating cooling processes for different materials.
