In this article, we have investigated thermal-diffusion and diffusion-thermo effects on unsteady flow of electrically conducting Eyring-Powell fluid over an oscillatory stretching sheet by using convective boundary conditions. A set of appropriate variables are used to reduce number of independent variables in governing equations. Series solution is computed using homotopy analysis method. The effects of various parameters of interest on the velocity filed, temperature profile, concentration profile, skin friction, local Nusselt number and local Sherwood number are illustrated graphically and discussed in detail.
A numerical study of unsteady hydromagnetic flow of Casson liquid passed through the oscillatory moving surface is presented. The interaction of radiation term is reported in the energy equation. The flow is generated by the rapid movement of elastic surface that stretched back and forth periodically. The number of variables is reduced by introducing dimensionless variables. An implicit technique developed on finite difference algorithm is implemented to the system of PDE. The impact of various parameters like Casson liquid parameter, the oscillation frequency and stretching rate ratio, Hartmann number and effective Prandtl number are shown through various graphs. The observation indicates that the amplitude of the velocity declines by enhancing Casson liquid parameter, oscillation frequency and stretching rate ratio and Hartmann number. The temperature declines by increasing Casson fluid parameter and effective Prandtl number. The results also indicate that the time-series of local Nusselt number increases by enhancing effective Prandtl number.
This novel investigation deals with the thermal slip in magnetized
axi-symmetric flow of Oldroyd-B liquid configured by infinite stretchable
disks. With appliance of fundamental laws, the flow model equations are
constructed. The governing flow equations are altered into no-dimensional
form by using similarity quantities. The solution procedure is followed by
using famous homotopy analysis technique. The convergence analysis is
performed to evaluate the solution accuracy. The signifi?cance of flow
parameters in the pattern of velocity, temperature and concentration are
graphically illustrated. The novel numerical simulations for wall shear
stress, Nusselt number, and Sherwood number are also performed at both
surfaces of disks. It is noted the effects of relaxation time and
retardation constants on radial and normal velocity components is opposite.
The thermal slip parameters enhance the nanoparticles temperature. The
concentration profile is decreases with Brown?ian motion parameter.
