An accurate, fast, mathematically robust, universal, non-iterative algorithm for computing multi-component diffusion velocities
Abstract
Using accurate multi-component diffusion treatment in numerical combustion studies remains formidable due to the computational cost associated with solving for diffusion velocities. To obtain the diffusion velocities, for low density gases, one needs to solve the Stefan–Maxwell equations along with the zero diffusion flux criteria, which scales as
