Abstract
Abstract In the production of ethelene glycol, graphene nanoparticles is inevitable and even suggested due to monomolecular layer of carbon atoms which are bounded like honey comb structure is known as graphene due to this structure, graphene has several types of exceptional and unique structural, optical and electronic properties. However, little is known on the enhancement of the transport phenomenon when Joule dissipation, inclined magnetic field, thermal jump and partial slip are apparent. With emphasis to the inherent aforementioned concepts together with heat source/sink and thermal radiation, this paper presents insight into the dynamics of unsteady Ethelene glycol conveying graphene nanoparticles through porous medium. The dimensional governing equation was non-dimenzionalized using fitting similarity variables and solved the dimensionless equations using Runge-Kutta Fehlberg algorithms along with the shooting technique. Also, a statistical method was implemented for multiple quadratic regression estimation analysis on the numerical figures of wall velocity gradient and local Nusselt number to establish the connection among heat transfer rate and physical parameters. Our numerical findings reveal that the magnetic field and porosity parameters boost the graphene Maxwell nanofluid velocity while Maxwell parameter has a reversal impact on it. The regression analysis confers that Nusselt number is more prone to heat absorption parameter as compared to Eckert number. The rate of heat transfer is higher in case of with slip compare to without slip flow in the presence of thermal radiation, viscous dissipation and unsteady parameter. The fluid velocity and temperature distribution is higher in without slip compare to with slip flow.

Summary
Abstract: In the production of ethelene glycol, graphene nanoparticles is inevitable and even suggested due to monomolecular layer of carbon atoms which are bounded like honey comb structure is known as graphene due to this structure, graphene has several types of exceptional and unique structural, optical and electronic properties. The e ect of viscosity is ignored but in the practical situation its e ect has a novel role Mamatha et al [32] and due to viscosity, viscous dissipation impact has not been considered as the same is supposed to be low but its relevance in food processing, instrumentations, lubrications, polymer manufacturing, etc., is considered as very signi cant as it enhances the characteristics of temperature distribution which induce the heat transfer rate. Sequel to the aforementioned published facts, it is worth remarking that there is no report on the signi cance of Joule dissipation, thermal jump, and partial slip on the dynamics of unsteady Ethelene glycol conveying graphene nanoparticles through a porous medium. The prevailing mathematical equations related to momentum and energy for the Maxwell nano uids problem by Mukhopadhyay [46] under the assumptions as considered above are expressed as
