MHD slip flow and heat transfer of UCM fluid with the effect of suction/injection due to stretching sheet: OHAM solution

Heat Transfer, 2022
AbstractIn this study, the optimal homotopy analysis (OHAM) technique has been examined to solve the laminar magnetohydrodynamic flow (MHD flow) on the upper‐convected Maxwell fluid on an isothermal porous stretch surface. A study on the effects of parameters like the relaxation time, suction/injection velocity, as well as the magnetic number on ...

Hydromagnetic mixed convective flow over a wall with variable thickness and Cattaneo-Christov heat flux model: OHAM analysis

Results in Physics, 2018
The effect of Cattaneo-Christov heat flux model for the hydro-magnetic mixed convective flow of a non-Newtonian fluid is presented. The flow over a wall having variable thickness is anticipated under the influence of transverse magnetic field and ...

Nonlinear Heat Transfer in a Two-Layer Flow With Nanofluids by OHAM

Journal of Heat Transfer, 2013
The problem of fully developed steady, laminar, incompressible flow in a vertical channel is studied analytically, one region is filled with water based copper nanofluid and the other region is filled with clear viscous fluid. The resulting coupled nonlinear ordinary differential equations (ODEs) are solved by optimal homotopy analysis method (OHAM ...

Application of OHAM to Couette flow of a third grade fluid

2016 7th International Conference on Mechanical and Aerospace Engineering (ICMAE), 2016
Two-layer Couette flow of a third grade fluid is studied. Optimal Homotopy Asymptotic Method is used to find solutions of coupled nonlinear differential equations governing the motion of two immiscible layers of fluids with equal thickness. The solution expressions are used to model the flow and to illustrate the effect of variable material constants ...

A novel formulation and analysis for heat transfer in von Kármán flow involving viscoelastic fluid: OHAM solutions

Journal of Thermal Analysis and Calorimetry, 2020
This research concentrates on the von Karman flow of viscoelastic fluid obeying second grade model over a heated permeable disk. Our interest is to explore how fluid motion triggered around the disk is affected by the existence of both elasticity and viscous dissipation effects.

Some Algebraic Approach for the Second Painlevé Equation Using the Optimal Homotopy Asymptotic Method (OHAM)

Numerical Analysis and Applications, 2018
Summary: In this paper, we introduced the optimal homotopy asymptotic method (OHAM) approach to propose analytic approximate solutions to the second Painlevé equation. The advantage of this method is that it provides a simple algebraic expression.
