Resumen:
A formulation based on the boundary-element method (BEM) to solve the conductive heat transfer problem between a particle and an adjacent heat exchange surface or between two particles is presented. This simple geometric configuration corresponds to a unit cell representing the thermal behavior near the wall or in the bulk of fixed and fluidized beds.The BEM is formulated by employing a variable number of nodes defined by the same quadrature points on which the integral coefficients of the influence matrix are evaluated. It is shown that this is a very efficient choice as compared to standard BEM formulations.
