🔥 Heat Transfer Calculators

Select a sub-discipline to solve thermal engineering problems using our high-precision, Fortran-powered calculators.

Conduction

Analyze steady and transient heat conduction through plane walls, cylinders, spheres, extended surfaces (fins), and thermal contact resistance.

Steady State Transient Fins

Convection

Calculate convective heat transfer coefficients and Nusselt numbers for external flows (flat plates, cylinders) and internal flows inside pipes or ducts under natural or forced convection.

Radiation

Determine thermal radiation heat exchange. Calculate blackbody emissive power, Wien's displacement law, view factors, gray enclosure radiosity networks, and radiation shields.
