The mixing length is a distance that a fluid parcel will keep its original characteristics before dispersing them into the surrounding fluid. Here, the bar on the left side of the figure is the mixing length. law of the wall, horizontal velocity near the wall with mixing length model. Meer weergeven In fluid dynamics, the mixing length model is a method attempting to describe momentum transfer by turbulence Reynolds stresses within a Newtonian fluid boundary layer by means of an eddy viscosity. The model was … Meer weergeven The mixing length is conceptually analogous to the concept of mean free path in thermodynamics: a fluid parcel will conserve its properties for a characteristic length, Meer weergeven • Law of the wall • Reynolds stress equation model Meer weergeven To begin, we must first be able to express quantities as the sums of their slowly varying components and fluctuating components.
