Heating rate equation

Web11 de abr. de 2024 · This leads to the following equation for heat release rate due to char oxidation: (10) Q ˙ c h ″ = χ ∙ h c h ∙ (1 − χ p y r) ∙ (m ˙ 21 % ″ − m ˙ 0 % ″) # By following this framework, it is possible to analyse the impacts of char oxidation on the burning of timber, where the energy is released, and the additional pyrolysis incurred. Web13 de abr. de 2024 · Modelling the self-heating of a microbolometer detector assumes that heat is generated in the detector layer by electrical power and then is transferred through all layer along the x-axis as shown in Figure 3. The model is simplified by applying the Laplace transform to the Fourier-Kirchhoff equation describing the heat conduction in solids.
