Hybrid nanofluid flow over a Stretching shrinking cylinder

Abstract

Hybrid nanofluid over a stretching/shrinking cylinder is an important ideal physical configuration of many practical applications. Traditional fluids such as water, ethylene glycol, engine oil and lubricants have low thermal conductivity, which gives a fundamental limit on heat transfer. Impact of Stefan blowing hybrid nanofluid flow over a stretching/shrinking cylinder with thermal radiation, stagnation point, variable viscosity, Joule heating, convective boundary condition, Soret and Dufour effect, MHD (magnetohydrodynamics), mixed convection, double stratification and velocity slip has been examined. Influence of mass diffusion also involved in this study of heat and mass transport phenomenon. newline newlineSimilarity transformations are employed to transform the governing partial differential equations into nonlinear ordinary differential equations. The transformed equations are then solved numerically by Bvp4c MATLAB solver. The flow features of heat and mass transfer characteristics for different values of the dimensionless parameters such as Stefan blowing parameter, thermal radiation parameter, magnetic parameter, Soret and Dufour number, Biot number, unsteadiness parameter, thermal and solutal stratification parameter, velocity slip and stretching/shrinking parameters are entangled in this study. Temperature profile, momentum profile, concentration profile, skin friction, Nusselt number and Sherwood number are analyzed and discussed in detail.
