The time-dependent flow past an impulsively started vertical infinite plate in a viscous electrically conducting natural convective incompressible Nano-fluid is considered in this article by taking into account the effects of heat absorption, heat generation and radiation. An analytical study is performed to obtain exact solutions for water-based Nano-fluid TiO2. The dimensionless governing equations for this investigation are solved analytically by using the small perturbation Technique. The effects of various physical parameters on velocity, temperature fields are presented graphically. With the aid of these, the expression for the skin-friction and Nusselt number profiles was done with the help of tables.
Analytical investigation is carried out to analyze the unsteady, two-dimensional, laminar, boundary layer flow of a viscous incompressible electrically conducting and heat absorbing fluid along a semi-infinite vertical permeable moving plate in the presence of Diffusion-thermo and radiation absorption effects. The set of ordinary differential equations are solved by using perturbation technique. The effects of the various fluid flow parameters on velocity, temperature and concentration fields with in the boundary layer have been analyzed with the help of graphs. Numerical values of local skin-friction coefficient, nusselt number and Sherwood number are tabulated.
The present work provides an analysis of the Dufour, radiation absorption, Hall and ion slip effects on MHD free convective rotating flow of Agwater based nanofluid past a semi-infinite permeable moving plate with constant heat source. In this regard, metal will be considered as nanoparticles with water as base fluid. Governing nonlinear boundary layer equations and boundary conditions are transformed into a system of nonlinear ordinary coupled differential equations and are solved by perturbation technique. Effects of different parameters on skin friction coefficient, local Nusselt number and Local Sherwood number are also discussed.
MHD Casson flow fluid over an inclined plate with aligned magnetic, Hall current and thermal radiation in the presence of Chemical reaction is examined. The governing equations are solved using perturbation method. The effects of various physical parameters like as chemical reaction parameter, radiation parameter, Casson parameter, Schmidt number, Grashof number, modified Grashof number, Prandtl number, magnetic parameter, inclined angle, Hall parameter and Aligned parameter are discussed for velocity, temperature and concentration. The skin-friction, Nusselt number and Sherwood number are also obtained and are shown in tabular form.
This article explains an influence of heat generation on MHD natural flow convective a vertical permeable surface with radiation. By using perturbation technique the equations of governing are converted to a system of non-linear O.D.E’S and are explained mathematically. Numerous physical limitations like M, F, Pr and some other parameters are studied through diagrams and tabular values. As conclusion of this investigation, decreasing in velocity profile as numerical standards increased in major cases except few effects like absorption radiation parameter R, Schmidt number Sc over velocity flow. The same effects are investigated for temperature profile as well as concentration profile
