    CMC-Computers, Materials & Continua, Vol.66, No.3, pp. 2253-2264, 2021, DOI:10.32604/cmc.2021.012470

    Abstract The present study is focused on the unsteady two-phase flow of blood in a cylindrical region. Blood is taken as a counter-example of Brinkman type fluid containing magnetic (dust) particles. The oscillating pressure gradient has been considered because for blood flow it is necessary to investigate in the form of a diastolic and systolic pressure. The transverse magnetic field has been applied externally to the cylindrical tube to study its impact on both fluids as well as particles. The system of derived governing equations based on Navier Stoke’s, Maxwell and heat equations has been generalized using the well-known Caputo–Fabrizio (C–F)… More >

    Peristaltic Flow of Dusty Nanofluids in Curved Channels

    Z. Z. Rashed1, Sameh E. Ahmed2,*

    CMC-Computers, Materials & Continua, Vol.66, No.1, pp. 1012-1026, 2021, DOI:10.32604/cmc.2020.012468

    Abstract In this paper, numerical investigations for peristaltic motion of dusty nanofluids in a curved channel are performed. Two systems of partial differential equations are presented for the nanofluid and dusty phases and then the approximations of the long wave length and low Reynolds number are applied. The physical domain is transformed to a rectangular computational model using suitable grid transformations. The resulting systems are solved numerically using shooting method and mathematical forms for the pressure distributions are introduced. The controlling parameters in this study are the thermal buoyancy parameter Gr, the concentration buoyancy parameter Gc, the amplitude ratio ϵ, the… More >
