This lecture covers the transient heat transfer regime, focusing on Newtonian heating and providing examples such as finite plates, infinite plates, and cylinders. It discusses the sudden change in thermal equilibrium, analytical and graphical solutions, and the density of heat flux. The lecture delves into the concept of Biot number, illustrating the importance of internal resistance in solids compared to contact resistance with the medium. It also explores the implications of Biot number on thermal resistance and the temperature profiles at boundaries. The lecture concludes with practical applications, including cooling of metal, and the significance of Fourier and Bessel functions in solving heat transfer problems.
