Radiative heat transfer calculator

Two bodies transfer heat via radiation to each other and the environment.



This calculator determines the temperature transients and heat fluxes in the system.

Step 1a Input data for body 1

Initial temperature [K]
Heat generation [W]
Surface Area [m2]
Emissivity [-]
Heat capacity [J/K]
View factor 1->2 [-]
Constant Temperature


Step 1b Input data for body 2

Initial temperature [K]
Heat generation [W]
Surface Area [m2]
Emissivity [-]
Heat capacity [J/K]
Constant Temperature


Step 2 Input data for enclosure

Initial temperature [K]
Surface Area [m2]
Emissivity [-]
Heat capacity [J/K]
Constant Temperature

( to approximate an infinite enclosure, input a very large surface area and an emissivity of 1)

Step 3 Input simulation time

Simulation time [s]


Step 4 Calculate
