Reyonlds-Averaged Navier-Strokes (RANS) equations are time-averaged equations of motion used to describe turbulent fluid flow.  To derive the equation, Reynolds decomposition must be used. Reynolds decomposition separates the flow variable into the mean and the fluctuating component as shown below. `u = obrace(baru)^(\"mean\")…
