Abstract

This study provides exact analytical solutions for both steady-state and pulsatile annular flows in coaxial cylindrical systems. It also examines the effects of a synchronized inner tube high velocity jet and its potential impact on annular blood flow. The presence of such fluid jet significantly enhances the velocity profile and flow rate across the annular section. These models offer valuable insights into optimizing flow performance in potential cardiovascular applications.
