Numerical simulations of radiative heat transfer in cylindrical participating enclosures using the finite volume method

In this work, radiative heat transfer in participating cylindrical enclosures is investigated using the Finite Volume Method (FVM). First, several test benches of absorbing, emitting and non-scattering gray media are studied. The predicted wall radiative heat fluxes, of all these cases, are compared to published experimental and numerical results. It is especially shown that the FVM and the DOM feature similar predictions when similar angular discretizations are used. However, the advantage of the FVM lays on its flexibility and liberty of choosing the angular discretization scheme, which makes it more useful in complex geometries. Therefore, and in a second part of this work, the FVM has been used to study a real Gas Turbine Combustor Simulator (GTCS) case which has extensively been studied by experimental measurements and DOM computations. The obtained FVM results featured good agreements with the experimental data especially when the measurement uncertainties are taken in consideration in the calculations. Finally, the GTCS radiative source term field is computed and presented.
