Abstract

To simulate the casting process and estimate casing defects, interface heat transfer coefficient is a necessary step towards it. For accurate simulation of any casting process the interfacial heat transfer coefficient (IHTC) or heat flux is required. IHTC value or Heat Flux value is vary essential which indicates the heat transfer at casting and mold surface interface. In any casting process, there are large number of factors which affects heat transfer and decreases quantification by theoretical means a challenge. Similarly,
Experimental methods applied directly to temperature data collected from castings are also a challenge to interpret because of transient nature of many casting processes. Many researchers have applied inverse methods to estimate interfacial heat transfer coefficient at metal-mold interface in sand casting process
