Significance of Lorentz Force and Thermoelectric on the Flow of 29 nm CuO–Water Nanofluid on an Upper Horizontal Surface of a Paraboloid of Revolution

Abstract

Combination of electric and magnetic forces on charged molecules of flowing fluid in the presence of a significant electromagnetic fields on surfaces with a nonuniform thickness (as in the case of upper pointed surface of an aircraft and bonnet of a car which are examples of upper horizontal surfaces of a paraboloid of revolution—uhspr) is inevitable. In this study, the influence of imposed magnetic field and Hall effects on the flow of 29 nm CuO–water nanofluid over such object is presented. Suitable similarity variables were employed to nondimensionalize and parameterize the dimensional governing equation. The numerical solutions of the corresponding boundary value problem were obtained using Runge–Kutta fourth-order integration scheme along with shooting technique. The domain of cross-flow velocity can be highly suppressed when the magnitude of imposed magnetic strength and that of Hall parameter are large. A significant increase in the cross-flow velocity gradient near an upper horizontal surface of the paraboloid of revolution is guaranteed with an increase in the Hall parameter. Enhancement of temperature distribution across the flow is apparent due to an increase in the volume fraction.

Comprehensive Examination of the Three-Dimensional Rotating Flow of a Ucm Nanoliquid Over an Exponentially Stretchable Convective Surface Utilizing the Optimal Homotopy Analysis Method

“…Further, Tiwari and Das (2007) examined two-sided lid-driven differentially heated square cavity filled with nanofluids model which different form conventional Buongiorno (2006) model and explained behavior of particle size, momentum/thermal diffusivity, and temperature. Some recent attempts to describe in this direction are Mustafa et al (2016); Hayat et al (2017); Animasaun et al (2019); Prasad et al (2018); Vaidya et al (2019aVaidya et al ( , 2019b; Majdi et al (2019);Puroshotaman et al(2019) and Amini et al (2020).…”

Inherent irreversibility in a reactive and radiating magnetic nanoliquid film along a slippery inclined heated surface with convective cooling

“…They arrived at the magnetic susceptibility of nanofluids showed provoking nature toward copper as compared to Alumina. Animasaun et al 7 considered combined effects of an imposed magnetic field and Hall effects on the flow of 29 nm CuO‐water nanofluid. They concluded that the domain of cross‐flow velocity could be suppressed when the imposed magnetic strength and that of Hall parameter are large.…”

“…Angayarkanni and Philip [40] presented a review on the thermal properties of nanofluid with some current developments. Several studies has been carried out for nanofluid inside parallel walls [41][42][43][44][45][46][47][48][49][50][51][52].…”
