Steady blood flow, or Poiseuille flow, through compressed or defective blood vessels presents critical challenges in hemodynamics, particularly in cardiovascular research. This study investigates a tube with a bipolar cylindrical cross section, a geometry relevant to unique hemodynamic issues such as blood flow through a bicuspid aortic valve during its oval systolic opening. A bipolar cross sectional analysis provides a more precise geometric approximation for modeling flow through such atypical vessel structures. In this paper, we derived an exact solution for the governing equations of Poiseuille flow within a bipolar cross sectional tube. The results encompass the velocity field, flow rate, and wall shear stress (WSS). The velocity profiles for blood flow in the bipolar cylindrical geometry demonstrate remarkable agreement with findings from previous studies utilizing coherent multi-scale simulations. |
