Radiative Heat Transfer in Finite Cylindrical Media — P1 Method

Application ID: 8571

These models use the Discrete Ordinates method (DOM) and P1 approximation to solve a 3D radiative transfer problem in an emitting, absorbing, and linear-anisotropic scattering finite cylindrical medium. Using the S6 quadrature of DOM leads to accurate results, which are needed in combined modes of heat transfer. The calculated incident radiation and heat fluxes agree well with published results obtained by transformed integral methods. The P1 approximation shows good agreement for large optical thickness by much lower computational costs. The DOM and P1 formulation in COMSOL Multiphysics also easily handle the effects of boundary emission and reflection.

This model example illustrates applications of this type that would nominally be built using the following products:
