WebAug 23, 2024 · Dear community, I am using the PDE toolbox to study the release of latent heat from a solid geometry. To do so, I need to set the internalheatsource in the thermal model. Is this energy per unit volume [J/m3] or power per unit volume [W/m3]? In general, is there any place where the units of measure used in the toolbox are clearly declared? WebTo do so, we would use the equation Q = m•C•ΔT. The m and the C are known; the ΔT can be determined from the initial and final temperature. T = T final - T initial = 85°C - 15°C = 70.°C With three of the four quantities of …
