WebThe void fraction, , depends on the prevailing flow patterns. The homogeneous void fraction model over-predicts the kinetic energy, while the selected separated flow models under-predict the kinetic energy. Thus an effective void fraction was recommended by modifying the homogeneous model. WebSep 7, 2010 · Void fraction is related to Slip Ratio S by the equations: (1) where U G and U L are the superficial velocities of the gas and liquid phases, p L and p G the liquid and gas densities and x the flow quality (see article on Multiphase Flow for definitions). For a homogeneous flow, S = 1 and: (2) where β is the volume flow fraction of the gas phase.

WebFormal definition. A flow on a set X is a group action of the additive group of real numbers on X.More explicitly, a flow is a mapping: such that, for all x ∈ X and all real numbers s … Flow Fraction (FF) = dialysate flow rate/blood flow rate (Q d /Q b ). As a result, the lower the Q d is, the lower the FF and the more saturated the dialysate will be. FF prescribed tend to range from 0.2 to 0.5. At a FF of 0.2 for example, dialysate saturations of urea and creatinine are approximately 95% and 90%, respectively.
