A time splitting least-squares finite element method (LSFEM) and the ‘stiff ODEs’ solver LSODE are used to simulate the advective transport of reactive species. Specifically, the rotating cone problem with chemical reactions serves as a model to

Numerical solutions of 3-D time-dependent Rayleigh-Benard convection are presented in this work. The temporal, spatial and thermal features of convective patterns are studied for four different geometric aspect ratios, 2:1:2, 4:1:4, 5:1:5 and 3.5:1:2

We present a least-squares finite-element method that can provide implicit, fully coupled transient solutions for time-dependent incompressible fluid flows and thermal convection. The algorithm consists of the Crank-Nicolson scheme for time discretiz

A least-squares finite element method (LSFEM) is used for the numerical solution of the advective transport of pollutants. Unlike many finite element methods, LSFEM does not involve any tuning parameter or intrinsic time function. Furthermore, LSFEM
