a balanced market is very difficult to achieve, because of changes in demand due to the evolving technology in the various applications. The Balance Problem is related to the volumes of the individual REEs consumed rather than the actual market value of an application. For instance, lamp phosphor...
You can calculate the magnitude of the fluctuating component from the Turbulence Kinetic Energy. If you look it up in the documenation, you'll see that the turbulent kinetic energy (k) is defined as: k=1/2*u^2 where u is the fluctuating component of velocity. Based on this you can est...
An algorithm was proposed to calculate the opening effectiveness of natural ventilation by Nääs et al. [37]: ϕ = AEVw/2. (9) 2.2.2. Displacement Ventilation The wind-induced ventilation rate of greenhouses with side and roof vents (Figure 1 (displacement ventilation)) can be ...
there are also other factors that determine the permeability and inertial coefficient: interpolation details, wall boundary layer effects, entrance/exit effects, dependency of the velocity range over which the quadratic correlation is taken to calculate permeability and the inertial coefficient, for example...
