Sažetak
In the present study, it is proposed to investigate ice formation of natural convection and variously located cylinder arrangements in a cooling storage rectangular tank with filled water. For this purpose a Fluent package program was used to solve a flow domain with unsteady state conditions. Ice formation shapes and temperature distributions were shown. Water temperature in the tank and surface temperature of cylinders were taken as 4 oC and -10 oC respectively. Staggered and inline cylinder geometries were investigated for temperature distribution, velocity vectors and ratio of Aice/Acylinder (ice area/cylinder cross sectional area) by changing transversal and longitudinal spacing.
