Numerical Computation of the Heat Transfer Coefficient in the 2-D Inverse Design Stefan Problem.

This paper presents an example of the application of a genetic algorithm to a 2-D design problem, which consists in the reconstruction of the function that describes the convective heat transfer coefficient, when the position of the moving interface of the phase change is well-known. In numerical calculations the Tikhonov regularization, the genetic algorithm and the alternating phase truncation method were used. The featured examples of calculations show a very good approximation of the exact solution and the stability of the procedure. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR]
