Effect of one vessel and two vessel model parameter sweeps on PVS fluid velocity. a One vessel model PVS peak fluid velocity as pulse amplitude varied. b One vessel model PVS peak fluid velocity as PVS inner radius varied for a range of outer radius values. Fluid velocity for R1 shown (see Fig. 1). c Two vessel model arterial and venous PVS peak fluid velocity as pulse amplitude varied for a range of venous to arterial pulsatility ratios, ξ. d Two vessel model arterial and venous PVS fluid velocity as arterial and venous pulse timing (phase shift, \(\theta\)) varied
