A Fluidized Bed Combustion Heat Transfer Model Using Finite Elements Free

This paper deals with the analysis of the axisymmetric heat transfer which occurs in a cylindrical combustion chamber using the finite element technique. The formulation of the equations used in the finite element method presented in this paper begins with the derivation of the heat conduction in three-dimensional polar coordinates. Through a series of transformations, the Poisson’s equation is numerically integrated to obtain the surface temperatures and overall heat transfer rates for the fluidized bed model. Several examples are given to demonstrate the application of the finite element principles to a thermal problem.
