Hybrid Method for Determination of Thermal Diffusivity of Liquid Flowing in a Pipe

Abstract

The paper deals with determination of thermal diffusivity of liquid flowing in a pipe based on inverse problem. The hybrid method was developed to improve the inverse solution. The proposed method is a combination of the artificial neural network and inverse solution algorithm. The artificial neural network is adopted for making a good initial-guessed value for the inverse solution. Numerical examples are included to demonstrate the performance of the proposed method. In comparison with the simple inverse solution, the proposed hybrid method is efficiently converged to yield good estimates.
