Numerical study and ANN-based prediction for Stefan-type Outward Ablation in one-dimensional cylindrical geometry

The one-dimensional heat transfer in a cylindrical ablating material is analysed for application in the aerospace and nuclear industries. To cause ablation, a heat flux of know magnitude is applied to the inner surface of the cylinder, while the outer surface is considered to be a convective boundary exposed to a coolant maintained at constant temperature. By utilizing the below provided data, parametric study is conducted to observe the effects of Stefan number and Biot number on the recession rate of the ablating cylinder. An ANN is also provided to swiftly predict the ablated material thickness for specified time and input parameters.
