... with Gauss–Seidel iterative approach is used to solve the coupled governing equations of momentum, energy, nanoparticle concentration and microorganism density. Darcy porous medium model is used in momentum equations. The effects of key dimensionless parameters, including the Peclet number, buoyancy ratio...

... on the subject. The motivation to work on boundary elements resides in the fact that when applying the first two mentioned approaches, several numerical problems such as oscillations and smoothing of wave fronts have been reported. A large number of authors have solved the problem for a low local Péclet number...
