RadiativeConvective helps you quickly check heat transfer in parts. It shows what share of thermal power sits inside any wavelength band, handy for filters and sensors. You can estimate total heat loss from both glowing and airflow at the same time. It tells you the surface temperature needed to reach a target radiated power. Model two facing surfaces in a box to find inner wall temps and net heat flow. Add sunlight: see net heat gained from α·G after basic losses. Get a quick cooling time by radiation, plus the peak glow wavelength from Wien’s law. Turn heat flux into temperature rise over time, fit emissivity from test data, and track how ΔT changes power.
