Abstract
The interfacial heat transfer coefficient (IHTC) is an important factor for precise simulation of casting simulation of heat transfer in castings. The large number of aspects prompting heat transfer renders 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. Inverse methods offer a solution and have been applied successfully to predict IHTC in many cases. Chill material, chill size or thickness, superheat, chill surface roughness, chill cooling conditions etc. are different parameters which have significant effect on heat transfer at casting-chill surface interface
