ABSTRACT

This paper contains novel model using feedback neural networks for a work piece temperature predic- tion.The heat and mass transfer in a porous metal workpiece which is heated by a fire gun is studied. The heat flux distribution is determined by thermocouple connected on the workpiece at definite distances. The gun work piece distance were also change and the temperature distribution and heat flux were determined. The permeability’s were in range of 0.01 – 0.15 .The ANN model parameters of the result output were simu- lated using the ANN parameters The simulation was done using MATLAB 6.0® Neural Network Toolbox.
