Transient evolution of temperature distribution along the position axis over time

Description

This figure depicts the transient evolution of temperature distribution along the position axis over time, illustrated as a heatmap with a coolwarm colormap ranging from blue (low temperature) to red (high temperature), overlaid with black isotherm contours and white arrows indicating heat flux vectors. It highlights the propagation of the thermal front and the directional heat flow, revealing key patterns in the spatiotemporal dynamics of the heat transfer process.
