Multi-Phase Nano Fluid Natural Convection in A Partially Divided Cavity for Cooling of Radioactive Waste Containers

The innovation of this investigation is fins arrangement effects on Al2O3-water Nano fluid natural convection in a partially divided cavity for energy storage systems and cooling radioactive waste containers. Simulation velocity temperature fields done based the Lattice Boltzmann Model using D2Q9 D2Q5 methods, respectively. Streamline, isotherm, Nusselt number, have been studied different shapes fins. In investigation, we surveyed 4 shape that arranged three cases; case 1: yL=0.25 L, yR=0.75 2: yL=0.5 yR=0.5 L Case 3: yL=0.75 yR=0.25 L. results illustrated, assuming base case, so with changing rate percentage average number cavities rectangular, circle, vertical horizontal Ellipse were %26, %8, %4 Furthermore, to these percentages %62, %24, %14 %22.
