Shape Factor & Enclosures in Radiative Heat Transfer

This course covers the comprehensive understanding of radiative heat transfer, focusing on the geometric configuration factor, shape factors, and their applications in engineering. It introduces the Monte Carlo method and Hottel's cross string method for complex situations and calculations. The course further explores the concept of radiative heat transfer in enclosures, discussing the empirical method for finding shape factors, estimation of radiative properties of surfaces, and the use of shields in temperature measurement. It also delves into the impact of spectral variation of properties on heat transfer, the design of tungsten filament lamps, and the challenges faced due to the non-gray nature of the surface. The course concludes with a discussion on the integral equation approach to radiative transfer in enclosures and the importance of the extinction coefficient in determining the mean free path of a photon.
