LEGENDRE, BESSEL AND BOUBAKER POLYNOMIALS THEORETICAL EXPRESSIONS OF LOW TEMPERATURE PROFILE IN A PYROLYSIS SPRAY MODEL: CASE OF GAUSSIAN DEPOSITED LAYER

In this paper, a solution to heat equation in a spherical model is proposed. The model takes into account conjointly the boundary conditions and the transfer equations in a spray device. The deposited layer is supposed to be Gaussian and not uniform like most recent studies. The solution, using Legendre, Bessel and Boubaker polynomials expansions, presents the advantage of being continuous and indefinitely derivable. These features make the resolution connectable to any heat transfer similar model.
