Making some assumption or simplification for computing the Reynolds stress z, is called the
modelling of turbulence. It is mainly classified by the number of transport equations for the turbulence quantity used for computation.
The equation for is called a zero-equation model. The equation for which the kinetic energy k of turbulence is determined from the transport equation, while the length scale E of turbulence is given by an algebraic expression, is called a one-equation model.
And the method by which both k and E are determined from the transport equation is called a two-equation model. The k-& model, using the turbulence energy dispersion E instead of I, is typical of the two-equation model.
As an example, Fig. 15.14 shows the mesh diagram used to compute the flow in a fluidic device and also the computational results of streamline, turbulence energy and turbulence dispersion.

is it true that a macbook wont be able to support the cad programs that are necessary?
solidworks course
Look in the help files of the program they are pretty comprehensive
