Heat Transfer Laboratory

A browser-based heat-transfer simulation for a steel ball dropped into boiling water. It runs on any operating system with no install.

Run

Open this file in a browser:

docs/index.html

To run it from GitHub: download the repo ZIP, extract it, then open docs/index.html.

What It Does

• Simulates a steel ball heating in a 100 C water bath.
• Generates a new randomized trial every time you press Start.
• Shows ball motion, water-field visualization, measured vs model temperature, and trial data.
• Exports results as CSV and the chart as PNG.

Controls

• Start: begin a new trial.
• Pause / Resume: freeze or continue the current trial.
• Reset: clear the run and return to the release position.
• Download CSV: export trial data.
• Export Chart: save the temperature chart.

Inputs

• Initial ball temperature: -20 C to 100 C
• Simulation time: 1 to 180 seconds

Model Note

The app uses a reduced-order lumped-capacitance model with randomized experimental variation:

T(t) = T_water - (T_water - T_initial) * e^(-hAt/mc)

It also includes a lightweight pseudo CFD-style water field for visualization. This is an educational simulator, not a full Navier-Stokes CFD solver.

Publish Online
