Analysis of Convective Transport of Temperature-Dependent Viscosity forNon-Newtonian Erying Powell Fluid: A Numerical Approach

Non-Newtonian is a type of fluid that does not comply with the viscosity under the Law of Newton and is being widely used in industrial applications.These include those related to chemical industries,cosmetics manufacturing,pharmaceutical field,food processing,as well as oil and gas activities.The inability of the conventional equations of Navier–Stokes to accurately depict rheological behavior for certain fluids led to an emergence study for non-Newtonian fluids’models.In line with this,a mathematical model of forced convective flow on non-Newtonian Eyring Powell fluid under temperature-dependent viscosity(TDV)circumstance is formulated.The fluid model is embedded with the Newtonian heating(NH)boundary condition as a heating circumstance and is assumed to move over a stretching sheet acting vertically.Using appropriate similarity variables,the respective model was converted into ordinary differential equations(ODE),which was later solved utilizing the Keller box approach.The present model is validated by comparing the existing output in literature at certain special limiting cases,where the validation results display a firm agreement.The current outputs for the proposed model are shown in tabular and graphical form for variation of skin friction plus Nusselt number,velocity and temperature distribution,respectively.

Mixed Convection of Non-Newtonian Erying Powell Fluid with Temperature-Dependent Viscosity over a Vertically Stretched Surface

The viscosity of a substance or material is intensely influenced by the temperature,especially in the field of lubricant engineering where the changeable temperature is well executed.In this paper,the problem of temperature-dependent viscosity on mixed convection flow of Eyring Powell fluid was studied together with Newtonian heating thermal boundary condition.The flow was assumed to move over a vertical stretching sheet.The model of the problem,which is in partial differential equations,was first transformed to ordinary differential equations using appropriate transformations.This approach was considered to reduce the complexity of the equations.Then,the transformed equations were solved using the Keller box method under the finite difference scheme approach.The validation process of the results was performed,and it was found to be in an excellent agreement.The results on the present computation are shown in tabular form and also graphical illustration.The major finding was observed where the skin friction and Nusselt number were boosted in the strong viscosity.
