碩士 === 國立成功大學 === 機械工程研究所 === 84 === The Monte Carlo method is applied to estimating thermal diffusivity of a one-dimensional homogeneous conductive medium. The Monte Carlo procedure consists of a fixed-step-direction and fixed-step-size random walk with the importance sampling technique. Psudo random number and quasi random number sequence are both employed in the random walks. The main advantage of the present method is that only one-single simulation of Monte Carlo is required to obtain the expression of the measured interior temperature in terms of the unknown thermal diffusivity. Two numerical examples and discussion of the influnces of different errors are involved in this work. Reducing the influnce of errors improves the result.
