| Abstract | ||
| A theoretical and experimental study was carried out on heat transfer through sand mould when the cast iron was poured in it .The experimental study includes manufacturing of sand mould and melting a quantity of cast iron in a furnace then pouring it in a sand mould , during this process thermocouples are fixed to measure temperature with time .The theoretical study includes the numerical solution of the equations of continuity, momentum and energy and programming in Qbasic to find out temperatures relation with time .A comparison is carried out between the two studies, there is a good agreement and connected relations among Nusselt number(Nu) ,Rayligh number(Ra), time, and radius(R). | ||
