AB The present article deals with the numerical study of two-dimensional steady-state laminar natural convection heat transfer inside an inclined solar collector with a V-corrugated absorber (hot wall) and a flat cover (cold wall). The Rayleigh number is considered to be lower than 5 × 10^{4} to satisfy the assumption of laminar region for the heat transfer problem. The governing continuity, momentum, and energy equations are converted to a quadrant domain by means of conformal mapping. The finite volume technique has been used for discretization of the equations using a staggered grid, and finally the SIMPLE algorithm is utilized to solve them. The effects of parameters such as the inclination angle, aspect ratio, wave parameter, and of the Rayleigh number on the local Nusselt and the mean Nusselt number have been considered. Patterns of heat and fluid flows are also simulated. The results show that there are conditions in which the mean Nusselt number could be optimized.
