It also has a moving fin in its top side. Three different cases are considered: a fixed fin (V = 0), a fin rotating clockwise (V+), and a fin rotating counterclockwise (V–). The cavity is heated and cooled from inclined walls and its bottom wall is adiabatic. Three-dimensional governing equations are solved by using the finite volume method. Other governing parameters are the Rayleigh number 103 ≤ Ra ≤ 106 and nanoparticle volume fraction 0.0 ≤ φ ≤ 0.15. It is found that heat transfer can be controlled via both a moving lid and particle addition into the base fluid. %8 2018-10-26
