Numerical and analytical solutions for Falkner-Skan flow of MHD Oldroyd-B fluid

Abstract

Purpose -In this paper, analysis is presented to investigate the Falkner-Skan flow of magnetohydrodynamic (MHD) Oldroyd-B fluid. The paper aims to discuss these issues. Design/methodology/approach -In this paper, the authors used two methods: homotopy analysis method and numerical Keller-box method. Findings -It is observed that skin friction coefficient in Oldroyd-B fluid is larger when compared with viscous fluid. Further, the relaxation and retardation times have opposite effects on the velocity components. Practical implications -A comparative study between the series and numerical solutions for the skin friction is shown in the paper. The results indicated that both solutions are in well agreement. Originality/value -This model is investigated for the first time, as the authors know.

Numerical study of MHD micropolar carreau nanofluid in the presence of induced magnetic field

“…He argued that, by increasing the velocity ratio parameter and magnetic number, the momentum boundary layer thickness declines. By considering the magnetohydrodynamic (MHD) Oldroyd-B fluid, Abbasbanday et al 3 reported the analytical solution of Falkner-Skan flow. They observed that the velocity components have reverse effects in relaxation and retardation times parameters.…”

Three-dimensional rotating flow of Jeffrey fluid for Cattaneo-Christov heat flux model

“…Since then various aspects of stretched flow problems have been investigated by several researchers. [18][19][20][21][22][23] In past most of the work is on the boundary layer flow with stretching surfaces where stretching velocity is directly proportional to the distance from the fixed origin. In such procedures simultaneous heating or cooling and kinematics of stretching have vital impact on the quality of the final product.…”
