ApacheSim is a dynamic thermal simulation program based on first-principles mathematical modeling of the heat transfer processes occurring within and around the building and is capable of solving problems of thermal insulation (type and placement), dynamics and thermal mass, building massing and orienta...
Thermal mass is the ability of a material to absorb, store, and release heat. Used to moderate building temperatures by reducing fluctuations, the concept is crucial in improving energy efficiency. Materials with relatively high thermal mass, such as stone, concrete, rammed earth, and brick, can...
For liquid 4He, the number density and mass are comparable to those for 3He, so that the transition temperature is of order 1 K. Nevertheless, the physics of the Bose–Einstein condensation is quite different from the onset of Fermi degeneracy, and we now explore the specific cases of a ...
In the current work, the unsteady thermal flow of Maxwell power-law nanofluid with Welan gum solution on a stretching surface has been considered. The flow is also exposed to Joule heating and magnetic effects. The Marangoni convection equation is also p

(Tinside,wall) can be queried at the level of 3D vertices from the generated 3D spatio-thermal mesh models. Thus, the building surface areas that are likely to suffer from condensation problems are directly detected by comparingTinside,wallandTDat the level of 3D points. Here, the building ...
The actual structure was modeled in the CFD model (Zhou et al., 2014) to validate the effect of hot helium mixing and to obtain the pressure drops with various mass flow rates by describing every detail inside. To save computational costs in current vertical gap bypass flow problem, it was...
The small courtyards were effective to cool the high thermal mass structures through nocturnal ventilative and radiative cooling. When assessed using an adaptive thermal comfort equation for hot–humid climates, the periods of indoor operative temperatures exceeding the 80% comfortable upper limit in ...
