· (uu) = −1∇p ρ + 1∇ ρ· (2µS) + f + 1 Fs ρ (2) where u is the velocity of flow; t is time; ρ is the flow density; p is the space pressure; µ is the dynamic viscosity of flow; S is the viscous stress tensor; f is the force per unit mass; Fs ...
In this way, the damping force for the enlarged plate with trivial boundary conditions has the same value as the damping force of the real device size considering the border effects [25]. Naturally, the border effect depends on the geometry of the gas outlet region. As the sealed device ...
At higher temperatures, a positive effect on the performance of the membrane-based heat exchangers is expected due to the more significant driving force between two air streams on either side of the membrane. Figure 6a–c shows that the range of change in sensible efficiency for all membranes ...
To bridge these gaps, this study investigated the relationship between PM2.5 concentrations and depressive symptoms in China using data from the 2016 wave of the China Labourforce Dynamics Survey (CLDS 2016). We further examine whether neighbourhood social capital has a protective influence on the ...
