Before looking at derived parameters such as collision potential, it is important to examine variables common among all flows. Pressure coefficient is one such parameter, and it is defined as:

FLUENT allows the pressure coefficient to be plotted, but the user must be careful to set the correct reference values. In this case, p0 = 0 (gauge pressure), ρ = 1000 kg/m3, and V = 0.1 m/s. Figure 2 shows the contours of pressure coefficient for flow around fifteen baffles.
