| 1 | Axisymmetric Powell-Eyring fluid flow with convective boundary condition: optimal analysis显示文摘The effects of axisymmetric flow of a Powell-Eyring fluid over an impermeable radially stretching surface are presented. Characteristics of the heat transfer process are analyzed with a more realistic condition named the convective boundary condition.Governing equations for the flow problem are derived by the boundary layer approximations. The modeled highly coupled partial differential system is converted into a system of ordinary differential equations with acceptable similarity transformations. The convergent series solutions for the resulting system are constructed and analyzed. Optimal values are obtained and presented in a numerical form using an optimal homotopy analysis method(OHAM). The rheological characteristics of different parameters of the velocity and temperature profiles are presented graphically. Tabular variations of the skin friction coefficient and the Nusselt number are also calculated. It is observed that the temperature distribution shows opposite behavior for Prandtl and Biot numbers. Furthermore,the rate of heating/cooling is higher for both the Prandtl and Biot numbers. | T.HAYAT S.MAKHDOOM M.AWAIS S.SALEEM M.M.RASHIDI | 2016 | Applied Mathematics and Mechanics(English Edition)2016，37，7： | 0 |
| 2 | Unsteady Squeezing Flow of Jeffery Fluid between Two Parallel Disks显示文摘We investigate an unsteady axisymmetric flow of a Jeffrey fluid between two parallel disks.The relevant partial differential equations are modeled and simplified by using appropriate transformations.The resulting ordinary differential system is solved and a series solution is obtained.Effects of various parameters of interest on the flow quantities are seen.It is found that the velocity profile increases when porosity and squeezing parameters are increased. | A.Qayyum M.Awais A.Alsaedi T.Hayat | 2012 | Chinese Physics Letters2012，29，3： | 0 |
| 3 | Newtonian heating in stagnation point flow of Burgers fluid显示文摘The Newtonian heating effects in the stagnation point flow of a Burgers fluid are addressed in this paper. The boundary layer flow problems are stated in the spatial domain from zero to infinity. The solution expressions for the velocity and the temperature are obtained and examined for the influential variables. The tabulated values show comparison with the previous results. It is observed that the obtained results are in good agreement with the existing results in limiting sense. | T.HAYAT S.ALI M.AWAIS M.S.ALHUTHALI | 2015 | Applied Mathematics and Mechanics(English Edition)2015，36，1： | 0 |
| 4 | Numerical Analysis of Magnetohydrodynamic Navier’s Slip Visco Nanofluid Flow Induced by Rotating Disk with Heat Source/Sink显示文摘Current exertion is made to depict and search out the flow features imparted to viscid fluid flow over a rotational disk. Impression of magnetic field with rotating fluid is generated by interacting it in radial direction.Nano structured particles with magnetized fluid are also incorporated in the upshot of chemical reaction and absorptive/generative heat induction. Von Kumaran procedure is executed to obtain flow narrating differential expressions.Flow pattern regarding thermal, momentum profiles are comprehended with the support of shooting method and RungeKutta methods. Furthermore, to get more realistic view of result description computational algorithm is modified by improving Runge-Kutta coefficients with Cash and Carp method. The aspects of flow controlling parameters like momentum slip parameter, magnetic strength parameter, Brownian motion parameter, thermophoresis parameter are adorned in sketches. Findings of these architects are accumulated in conclusion section. | M.Awais S.Bilal M.Y.Malik Khalil-ur-Rehman | 2019 | Communications in Theoretical Physics2019，71，9： | 0 |

| 6 | f(G,T) Gravity with Cylindrically Symmetric Relativistic Fluids显示文摘The aim of this paper is to examine the structure scalars with account of f(G, T) theory of gravity. We consider the cylindrically symmetric spacetime with dissipative anisotropic background. We have determined the structure scalars by orthogonally decomposing the Riemann curvature tensor and it is shown that these scalars are associated with fundamental properties of fluid. We further investigate the mass function along with the transport equation and discuss their role on the evolutionary stages of relativistic stellar systems. We have also analyzed these structure scalars for static fluid distributions and it is concluded that all possible solutions of field equations can be expressed through these scalars. | M.Farasat Shamir M.Awais Sadiq | 2019 | Communications in Theoretical Physics2019，71，2： | 0 |
