ABSTRACT
Emissivity is a parameter which helps to determine emissive power of a Surface. Much experimental work in radiation has been done to find out the value of emissivity for different surfaces. The paper reports the ability of Bayesian Approach and least square method in parameter estimation when radiation heat transfer is encountered. The aim is to estimate the value of Emissivity of material using Bayesian optimization method and least square residual method where air is used as a working medium. The steady temperature time history is mainly used to estimate Emissivity of material in Bayesian and least square optimization method. The experimental setup has been designed and fabricated. Finally, Estimated Parameter is compared with Actual benchmark.
