Numerical tests demonstrate that the DRM successfully removes false scattering in all the two - dimensional test problems discussed in this paper. The effect of false scattering on the computational results in two - dimensional situations is investigated with the DRM. False scattering plays a double role : when the boundary emits radiation in a limited number of directions, or when the irradiation comes from a limited number of directions, it produces a smeared intensity field and radiative heat flux distribution, and thus must be removed. In the case of diffuse boundary, however, false scattering plays a useful role and thus should be retained. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
