The units in brackets [m^2s^-2] implies that it is velocity to the power 2. It cannot refer to the entire expression (p/36) as then the density expression is dimensionally incompatible. So presumably 36.0 has the units [m^2s^-2].

The term p/(v^2/2) has the units of density. Perhaps it has something to do with your pulsatile velocity and the corresponding pulsatile pressure. But there cannot be any density variations as your flow is incompressible.

Does CFX give this value for density of blood? Another question is 'Is it correct for the applied inlet velocities and applied outlet pressures to be in phase?' In pulsatile flows, the capacity must also enter the picture. These are general comments.
