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:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products.
