Introduction to Turbulence Modeling

Pressure-Strain Correlation

Modeling the pressure-strain correlation, , is critical to the stress transport equations.

Navier-Stokes Equation

(1)

Taking the divergence of (1), we find

(2)

or

(3)

Averaging Equation (3), the result is:

(4)

Subtracting (4) from (3), we find

(5)
