Temperature Rise Calculator

This app simulates the temperature rise of a real physical object heated from within, using first-principles thermodynamics and models how heat flows into an object from an internal power source and how heat is lost to the environment through: • Convection to surrounding air • Thermal radiation • Conduction to a supporting surface The system is treated as a lumped thermal mass, making it ideal for compact objects such as aluminum plates, enclosures, or electronic assemblies. What the app does • Solves the governing heat-balance differential equation • Displays temperature vs. time graph • Computes the steady-state temperature (T∞) • Estimates the thermal time constant (τ) • Exports temperature data to CSV for further analysis • Exports temperature vs time graph to PNG The temperature response, naturally, follows a first-order behavior. Adjustable parameters: • Heater power • Object mass and material properties • Surface area • Convective heat transfer coefficient • Emissivity • Conduction path length • Ambient and contact temperatures Who this app is for: • Engineers and designers • Students learning heat transfer • Makers and experimenters • Anyone validating thermal behavior against real measurements This app focuses on physical correctness, not curve-fitting — making it suitable for both education and practical engineering intuition. Notes: • Assumes uniform internal temperature (lumped-parameter model) • Best suited for small to medium-sized objects • Results are intended for analysis and insight, not safety-critical design!
