Peripheral layer viscosity effects on periodic blood flow through rigid tube of thin diameter
A 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 \textit{A. F. Elkouh} [J. Fluid. Eng. 100, 131 ff. (1978)]. The results obtained for velocity profiles have been compared with the experimental results. The effects of various parameters on wall shearing stress has also been brought out and discussed.
