The realisable k-3 model was chosen as the appropriate
model for calculation. It is an improved version of the normal
k-3 model and consists of two equations, the transport
equation for turbulent kinetic energy k and an equation for its
dissipation rate 3. The realisable k-3 model is more appropriate
for the calculation of the diffusion rate when there are
uniform fluid jets through the slots (Fluent, 2006).
