| 1 | MHD three-dimensional flow of Jeffrey fluid with Newtonian heating显示文摘The magnetohydrodynamic(MHD) three-dimensional flow of Jeffrey fluid in the presence of Newtonian heating is investigated. Flow is caused by a bidirectional stretching surface. Series solutions are constructed for the velocity and temperature fields. Convergence of series solutions is ensured graphically and numerically. The variations of key parameters on the physical quantities are shown and discussed in detail. Constructed series solutions are compared with the existing solutions in the limiting case and an excellent agreement is noticed. Nusselt numbers are computed with and without magnetic fields. It is observed that the Nusselt number decreases in the presence of magnetic field. | S.A.Shehzad T.Hayat M.S.Alhuthali S.Asghar | 2014 | Journal of Central South University2014，21，4： | 6 |

| 3 | Heat transfer analysis in peristaltic flow of MHD Jeffrey fluid with variable thermal conductivity显示文摘The effect of an inclined magnetic field in the peristaltic flow of a Jeffrey fluid with variable thermal conductivity is discussed. The temperature dependent thermal conductivity of fluid in an asymmetric channel is taken into account. A dimensionless nonlinear system subject to a long wavelength and a low Reynolds number is solved.The explicit expressions of the stream function, the axial velocity, the pressure gradient,and the temperature are obtained. The effects of all physical parameters on peristaltic transport and heat transfer characteristics are observed from graphical illustrations. The behaviors of θ∈ [0, π/2] and θ∈ [π/2, π] on fluid flow and heat transfer are found to be opposite. Further, the size of trapped bolus is greater for the case of the inclined magnetic field(θ = π/2) than that for the case of the transverse magnetic field(θ = π/2). The heat transfer coefficient decreases when the constant thermal conductivity(Newtonian)fluid is changed to the variable thermal conductivity(Jeffrey) fluid. | Q.HUSSAIN S.ASGHAR T.HAYAT A.ALSAEDI | 2015 | Applied Mathematics and Mechanics(English Edition)2015，36，4： | 3 |
| 4 | Heat transfer in a porous saturated wavy channel with asymmetric convective boundary conditions显示文摘The viscous flow in a wavy channel with convective boundary conditions is investigated. The channel is filled with a porous viscous fluid. Two cases of equal and different external convection coefficients on the walls are taken into account. Effect of viscous dissipation is also considered. The governing equations are derived employing long wavelength and low Reynolds number approximations. Exact closed form solutions are obtained for the simplified equations. Important physical features for peristaltic flow caused by the wavy wave are pumping, trapping and heat transfer rate at the channel walls. These are discussed one by one in depth and detail through graphical illustrations. Special attention has been given to the effects of convective boundary conditions. The results show that for Bi1≠Bi2, there exists a critical value of Brinkman number Brc at which the temperatures of both the walls become equal. And, for Bi1>Bi2 and Br>Brc, the temperature of the cold wall exceeds the temperature of hot wall. | Q.Hussain S.Asghar T.Hayat A.Alsaedi | 2015 | Journal of Central South University2015，22，1： | 2 |
| 5 | Hall and ion slip effects on peristaltic flow and heat transfer analysis with Ohmic heating显示文摘The peristaltic transport of a magnetohydrodynamic(MHD) fluid is examined for both symmetric and asymmetric channels. Hall and ion slip effects are taken into account. The heat transfer is analyzed by considering the effects of viscous and Ohmic dissipations. The relevant flow problems are first modeled, and then the closed form solutions are constructed under the assumptions of long wavelength and low Reynolds number. The solutions are analyzed through graphical illustration. It is noted that the velocity increases but the temperature decreases with the increases in the Hall and ion slip parameters. The axial pressure gradient is less in magnitude in the presence of Hall and ion slip currents. The Hall and ion slip effects are to decrease the maximum pressure against which peristalsis works as a pump. The free pumping flux decreases with the increases in the Hall and ion slip parameters. The increases in the Hall and ion slip parameters result in an increase in the size of the trapped bolus. | S.ASGHAR Q.HUSSAIN T.HAYAT F.ALSAADI | 2014 | Applied Mathematics and Mechanics(English Edition)2014，35，12： | 2 |
| 6 | Transient flows of Maxwell fluid with slip conditions显示文摘Two fundamental flows, namely, the Stokes and Couette flows in a Maxwell fluid are considered. The exact analytic solutions are derived in the presence of the slip condition. The Laplace transform method is employed for the development of such solutions. Limiting cases of no-slip and viscous fluids can be easily recovered from the present analysis. The behaviors of embedded flow parameters are discussed through graphs. | T.HAYAT S.ZAIB S.ASGHAR K.BHATTACHARYYA S.A.SHEHZAD | 2013 | Applied Mathematics and Mechanics(English Edition)2013，34，2： | 1 |

| 8 | Transient mixed convection flow arising due to thermal and mass diffusion over porous sensor surface inside squeezing horizontal channel显示文摘The double diffusion effect on the mixed convection flow over a horizontal porous sensor surface placed inside a horizontal channel is analyzed.With the appropriate transformations,the unsteady equations governing the flow are reduced to non-similar boundary layer equations which are solved numerically for the time-dependent mixed convection parameter.The asymptotic solutions are obtained for small and large values of the time-dependent mixed convection parameter.The results are discussed in terms of the skin friction,the heat transfer coefficient,the mass transfer coefficient,and the velocity,temperature,and concentration profiles for different values of the Prandtl number,the Schmidt number,the squeezing index,and the mixed convection parameter. | M.MAHMOOD S.ASGHAR M.A.HOSSAIN | 2013 | Applied Mathematics and Mechanics(English Edition)2013，34，1： | 1 |
| 9 | Computational study of combined effects of conduction-radiation and hydromagnetics on natural convection flow past magnetized permeable plate显示文摘The computational study of the combined effects of radiation and hydromagnetics on the natural convection flow of a viscous,incompressible,and electrically conducting fluid past a magnetized permeable vertical plate is presented.The governing non-similar equations are numerically solved by using a finite difference method for all values of the suction parameter ξ and the asymptotic solution for small and large values of ξ.The effects of varying the Prandtl number P r,the magnetic Prandtl number P r m,the magnetic force parameter S,the radiation parameter R d,and the surface temperature θ w on the coefficients of the skin friction,the rate of heat transfer,and the current density are shown graphically and in tables.An attempt is made to examine the effects of the above mentioned physical parameters on the velocity profile,the temperature distribution,and the transverse component of the magnetic field. | M.ASHRAF S.ASGHAR M.A.HOSSAIN | 2012 | Applied Mathematics and Mechanics(English Edition)2012，33，6： | 0 |
| 10 | Flow and heat transfer of a nanofluid over a hyperbolically stretching sheet显示文摘This article explores the boundary layer flow and heat transfer of a viscous nanofluid bounded by a hyperbolically stretching sheet. Effects of Brownian and thermophoretic diffusions on heat transfer and concentration of nanoparticles are given due attention. The resulting nonlinear problems are computed for analytic and numerical solutions. The effects of Brownian motion and thermophoretic property are found to increase the temperature of the medium and reduce the heat transfer rate. The thermophoretic property thus enriches the concentration while the Brownian motion reduces the concentration of the nanoparticles in the fluid. Opposite effects of these properties are observed on the Sherwood number. | A.Ahmad S.Asghar A.Alsaedi | 2014 | Chinese Physics B2014，23，7： | 0 |
