Heat Transfer
This interactive simulator explores Heat Transfer in Thermodynamics. Conduction, convection, and radiation with temperature gradients. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Thermodynamics.
Key terms
- heat
- transfer

How it works
A 2D **heat equation** on a grid: ∂T/∂t = α∇²T with fixed hot/cold vertical edges and weak top/bottom coupling. **Convection** shifts the temperature field horizontally (plug-flow style advection). **Radiation** adds a nonlinear cooling toward a mid temperature; **Newton cooling** is linear in (T − T_amb). Click the canvas to inject a hot pulse. This is a qualitative finite-difference demo, not a CFD solver.
