WebIn fluid dynamics, the law of the wall(also known as the logarithmic law of the wall) states that the average velocityof a turbulent flow at a certain point is proportional to the logarithm of the distance from that point to the "wall", or the boundary of the fluidregion. WebThe velocity of the mixture is solved for from a single momentum equation. For each phase, an individual continuity equation is solved for to obtain its volume fraction. In multiphase mixtures, gravity and centrifugal forces tend to cause velocity differences which have to …
