From: The effect of inlet and outlet boundary conditions in image-based CFD modeling of aortic flow
Axial velocity magnitude contours and tangential velocity vectors along planes normal to the centerline at streamwise coordinates of 0.5D and 1D, where D is the inlet diameter, during peak systole; a, d have parabolic velocity inlet conditions, b, e have linear shear velocity 1 inlet conditions, and c, f have linear shear velocity 2 inlet conditions. These simulations had no secondary flows at the inlets and all outlet boundary conditions were of the outflow variety
