| 1 | Impact of anisotropic slip on the stagnation-point flow past a stretching/shrinking surface of the Al2O3-Cu/H2O hybrid nanofluid显示文摘The characteristics of heat transfer in the three-dimensional stagnationpoint flow past a stretching/shrinking surface of the Al2O3-Cu/H2O hybrid nanofluid with anisotropic slip are investigated.The partial differential equations are converted into a system of ordinary differential equations by valid similarity transformations.The simplified mathematical model is solved computationally by the bvp4c approach in the MATLAB operating system.This solving method is capable of generating more than one solutions when suitable initial guesses are proposed.The results are proven to have dual solutions,which consequently lead to the application of a stability analysis that verifies the achievability of the first solution.The findings reveal infinite values of the dual solutions at several measured parameters causing the non-appearance of the turning points and the critical values.The skin friction increases with the addition of nanoparticles,while the escalation of the anisotropic slip effect causes a reduction in the heat transfer rate. | N.A.ZAINAL R.NAZAR K.NAGANTHRAN I.POP | 2020 | Applied Mathematics and Mechanics(English Edition)2020，41，9： | 0 |
| 2 | Unsteady flow of a Maxwell hybrid nanofluid past a stretching/shrinking surface with thermal radiation effect显示文摘The non-Newtonian fluid model reflects the behavior of the fluid flow in global manufacturing progress and increases product performance.Therefore,the present work strives to analyze the unsteady Maxwell hybrid nanofluid toward a stretching/shrinking surface with thermal radiation effect and heat transfer.The partial derivatives of the multivariable differential equations are transformed into ordinary differential equations in a specified form by applying appropriate transformations.The resulting mathematical model is clarified by utilizing the bvp4c technique.Different control parameters are investigated to see how they affect the outcomes.The results reveal that the skin friction coefficient increases by adding nanoparticles and suction parameters.The inclusion of the Maxwell parameter and thermal radiation effect both show a declining tendency in the local Nusselt number,and as a result,the thermal flow efficacy is reduced.The reduction of the unsteadiness characteristic,on the other hand,considerably promotes the improvement of heat transfer performance.The existence of more than one solution is proven,and this invariably leads to an analysis of solution stability,which validates the first solution viability. | N.A.ZAINAL R.NAZAR K.NAGANTHRAN I.POP | 2021 | Applied Mathematics and Mechanics(English Edition)2021，42，10： | 0 |
| 3 | Slip effects on unsteady mixed convection of hybrid nanofluid flow near the stagnation point显示文摘The unsteady mixed convection of the Al_(2)O_(3)-Cu/H_(2)O hybrid nanofluid flow near the stagnation point past a vertical plate is analyzed.The bvp4c technique is used to solve the resulting ordinary differential equations.The combined effects of the velocity and thermal slip are addressed.The effects of different relevant physical parameters are studied numerically.The results show that the heat transfer rate is reduced when the volume fraction of the nanoparticles increases,while the unsteadiness parameter has an opposite effect in the opposing flow.The presence of the slip parameter is proven to increase the skin friction coefficient while reduce the local Nusselt number in the buoyancy opposing flow.A contradictory result is observed in the buoyancy assisting flow.Meanwhile,the heat transfer rate is reduced in the buoyancy of the assisting and opposing flows when the thermal slip effect is considered. | N.A.ZAINAL R.NAZAR K.NAGANTHRAN I.POP | 2022 | Applied Mathematics and Mechanics(English Edition)2022，43，4： | 0 |
