Abstract

An approximate analysis of transient heat diffusion problem in two composite cylindrical media is investigated. A new formulation of the problem is introduced in which the outer layer of the composite cylinders is lumped by assuming a uniform temperature distribution throughout. The temperature, however, is allowed to vary with time. this assumption reduces the two layers problem to a one region problem with a new set of boundary conditions which compensates the effect of the lumped outer layer. The temperature distribution of the approximate formulation is than compared to the exact distribution obtained analytically. A" breakdown" criterion of the approximation is obtained.
