Numerical Study of mixed convection in square enclosure filled by air, which has two sinusoidal walls with different locations in outer walls, when a circular rotating cylinder is entered to the enclosure is being approached throughout this paper. A two dimensional, time independent, laminar mixed convection with variable Richardson number during the range from (0.1 to œ) at Ra=105 and D=0.4L by using Fluent ANSYS 16. The work goes further to study the location effects of sinusoidal walls which are changed vertically, horizontally and orthogonally. Stream function, isotherms, local and mean Nusselt number are chosen to represent the effects of velocity, temperature and heat transfer in the enclosure. The obtained numerical results explain that the design of orthogonal sinusoidal walls has high heat transfer than vertical and horizontal sinusoidal walls; besides, Nusselt number increases when Richardson number is increased.
