Combined convection flow over a vertical cylinder is studied by many researchers, but the flow around a yawed cylinder has not been examined yet, and that too by considering multiple (triple) diffusions, namely that of liquid oxygen, hydrogen, and heat. The equations representing such a mathematical model are obtained in terms of PDE being coupled and nonlinear. The equations are then dimensionless via non-similar transformations. The resulting nonlinear dimensionless coupled partial differential equations with boundary constraints are solved using the Quasi-linearization technique in conjunction with the implicit finite difference scheme. The graphs plotted for these numerical data reveal that the velocity of the liquid in chordwise (x-axis), spanwise (z-axis) directions and the corresponding frictions increase with the combined convection effect, whereas the liquid temperature lessens significantly. In aiding buoyancy flow case, the velocity of the fluids in chordwise along with spanwise directions, the drag coefficient along the chordwise direction and the rate of mass transfer increases due to the yaw angle. Also, the fluid temperature reduces along with the species concentrations increase with increasing values of yaw angle. The velocity pattern and drag coefficient augment with growing values of magnetic parameter. Also, the liquid temperature enhances, while the Nusselt number reduces for enhancing values of the Eckert number. To determine the efficacy of the numerical technique used, we compared the results to those previously published and found them to be very similar.
