Data for a moving heat source based on the DPL heat conduction model

The research hypothesis is that, under the dual-phase-lag (DPL) heat conduction model, the temperature field distribution in a material subjected to a moving heat source is strongly influenced by parameters such as source velocity, intensity, and phase-lag times. The data consists mainly of .mat files containing temperature fields (e.g., T.mat, T1.mat), spatial grids (e.g., x.mat, y.mat), and some analytical solution data, all generated by MATLAB simulations. Each .mat file contains variables such as T (temperature field as a 2D matrix), x and y (or r and θ for polar coordinates), and time steps, with physical parameters like diffusivity and phase-lag times set in the scripts. To use the data, load the .mat files in MATLAB, where each row/column of T corresponds to specific spatial coordinates given by x, y, r, or θ. Visualization can be done using MATLAB plotting functions, and researchers can modify the main scripts to generate new data for different parameter sets or to compare with analytical results. This dataset enables the study and validation of DPL heat conduction models under various moving heat source scenarios.
