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

Steps to reproduce
1. The contents of "program" text file need to be converted to MATLAB script in order to simulate the ablation process. 2. The ANN model is available for predicting the non-dimensional ablated material thickness (∆) for a given point in time and input parameters (Ste, Bi, Q, τ). 3. The trained ANN model for thick and thin cylinders are saved separately in ".h5" format, which needs to be reloaded in their respective notebooks before predicting. Also, make sure to normalize the input data before acquiring the prediction values.
