3Circular Flux Tubes and Disks
The heat transfer literature contains many solutions for thermal spreading resistance in cylindrical co‐ordinate systems for single isotropic materials, compound systems, orthotropic systems, and multilayered systems. This chapter focuses primarily on solutions for isotropic and multilayered systems with variable heat flux specified in the source region. Orthotropic systems will be dealt with in Chapter 5.
Single heat source spreading resistance and temperature field for finite disks and flux tubes has been examined in numerous published works [Kennedy (1960), Mikic and Rohsenow (1966), Yovanovich (1975), Yovanovich et al. (1980), Yovanovich et al. (1988), Song et al. (1995)]. Two of the most important solutions ...
