Non Fourier Heat Transfer Across a Gun Barrel

Abstract

In this project, study of hyperbolic heat transfer equation across a gun barrel is investigated. First, a comparison is made among several research work on parabolic and hyperbolic equations contributed in this field. Then, equations are formulated for non Fourier heat equations. These governing equations are normalized after which, a characteristic Peclet number is obtained which depends on local sound speed and thermal diffusion speed. A code was written in Matlab language for 3 different Peclet Numbers. Maccormack Predictor and Corrector algorithm was used to generate the program and plot graphs. The Peclet number is varied in the experiment, following which, a transition is seen from the hyperbolic nature to the parabolic curve.
