Numerical approximations for fluid flow and heat transfer in the boundary layer with radiation through multiple Lie similarity transformations

open access: yesFrontiers in Physics, 2023
The dependent or independent variables of differential equations may be reduced by applying its associated Lie point symmetries. Seven-dimensional Lie point symmetry algebra exists for differential equations representing heat transfer in a boundary layer

A Reduced Basis Method for Radiative Transfer Equation [PDF]

open access: yesJournal of Scientific Computing, 2022
Linear kinetic transport equations play a critical role in optical tomography, radiative transfer and neutron transport. The fundamental difficulty hampering their efficient and accurate numerical resolution lies in the high dimensionality of the physical and velocity/angular variables and the fact that the problem is multiscale in nature.
