Peripheral layer viscosity effects on periodic blood flow through rigid tube of thin diameter

AbstractA mathematical model has been presented for periodic blood flow in a rigid circular tube of thin diameter. Blood is presented as a 3-layered fluid by considering core fluid as a casson fluid which is covered by a thin layer of Newtonian fluid (plasma). The energy integral method has been used to obtain the unsteady pressure gradients as suggested by Elkouh [2]. The results obtained for velocity profiles have been compared with the experimental results of Bugliarello and Sevilla (Biorheology 7 (1970), 85). The effects of various parameters on wall shearing stress has also been brought out and discussed
