This chapter deals with the heat transfer characteristics between the cast and the mold. Generally the heat transfer behavior between the cast and the sand mold is used and all the three modes of heat transfer are studied. The heat transfer characteristics from the cast is at a faster rate for a die mold than for the sand mold. Since the sand mold is used for most of the industrial applications for the complex shapes of metal the heat transfer and the shrinkage behavior in solidification has to be understood perfectly. In this chapter, since the heat transfer mechanism and the shrinkage behavior of the metal in the sand mold is interrelated, hence were predominantly discussed.

In today’s world, the energy requirement has full attention in the development of any country for which it requires an effective and sustainable potential to meet the country’s needs. Thermal energy storage has a complete advantage to satisfy the future requirement of energy. Heat exchangers exchange heat in the thermal storage which is stored and retrieved later or can be used as a pre-heating or post-heating devices to save energy. Criteria of design of heat exchangers for various thermal energy storage applications along with their various components are being elaborated. The latent heat thermal energy storage in a mass application has got many advantages over the sensible heat storage. The existing approaches in the design, integration and application of phase change materials (PCMs) are explored by experimenting on a prototype of a single heat exchanger module and analysing all the design aspects to get a significant idea and the analysis needed while charging and discharging the heat exchanger.
