In this study, a new-fangled problem is considered, wherein, for the first time, the effects of mixed convection past a yawed cylinder are analysed. In reality, the concept of mixed convection flow past a yawed cylinder arises in applications pertaining to heat exchangers. To study the diffusion of heat in the mixed convection system, the problem is formulated mathematically in terms of partial differential equations which are nonlinear and coupled in nature. To avoid the mathematical complexity of dimensions, these equations are converted to dimensionless form through non-similar transformations. The linearity in the system of equations is achieved through Quasi-linearization technique. Then, implicit finite difference method is used for the discretization and the linear system of equations is solved by employing Varga's algorithm. The investigation reveals several important results pertaining to yaw angle, mixed convection and non-similarity phenomena. The fluid velocity and friction at the cylinder's surface in all directions increase along with the heat transfer rate due to mixed convection, while the fluid temperature reduces significantly. Yaw angle has prominent effects in increasing the fluid velocity in the chordwise (x-axis) as well as the spanwise (z-axis) directions in case of aiding buoyancy flow. © 2020 Elsevier Ltd
