WebJan 21, 2024 · We propose two models of the Boltzmann equation (BGK and Fokker-Planck models) for rarefied flows of diatomic gases in vibrational non-equilibrium. These models take into account the discrete repartition of vibration energy modes, which is required for high temperature flows, like for atmospheric re-entry problems.

"WebDerivation of Stefan Boltzmann Law The total power radiated per unit area over all wavelengths of a black body can be obtained by integrating Plank’s radiation formula. Thus, the radiated power per unit area as a function of wavelength is: d P d λ 1 A = 2 π h c 2 λ 5 ( e h c λ k T − 1) Where, P is Power radiated. " - Boltzmann and planck
