On two-phase model of pulsatile blood flow with entrance effects.
A particle fluid suspension model is applied to the problem of pulsatile blood flow through a rigid circular tube with entrance effects. Flow is generated by an arbitrary (time and axial flow variable dependent) as well as a particular pressure gradient of physical importance. Fluid and particle phase velocities are explicitly determined for both, with and without entrance effects. Further, steady pulsatile velocities for both cases are deduced by taking time t -greater than . Several other limiting cases of physical and biological importance have been obtained and discussed in detail.
