Melting heat analysis in squeezed flow of nanofluids (SWCNTs + Water, SWCNTs + Gasoline oil, MWCNTs + Water, MWCNTs + Gasoline oil) with Cattaneo–Cristov heat flux

This analysis emphasizes impacts of CNTs (Carbon nanotubes) during Darcy–Forchheimer squeezed flow. Melting heat transfer process is addressed. Water and gasoline are treated as baseliquid. By transformation method non-linear system of ODEs are obtained from the flow field equations (PDEs). Further the emerged flow problem is solved via OHAM. Influences of physical involved parameters on velocity, surface friction coefficient, temperature as well as Nusselt number are expressed graphically and interpreted physically.

Compressed Flow of Hybridized Nanofluid Entwined Between Two Rotating Plates Exposed to Radiation

The existing work unveils the mixed convection squeezed flow of MHD hybridized nanoliquid amid two plates of the channel that is rotating vertically depending upon time. The fluid is sucked/injected through the channel extremes. The hybrid nanofluid anticipated here is composed of Graphene oxide and Molybdenum disulphide with the hybrid base fluid comprised of water and ethylene glycol. The scrutiny is carried out in the presence of thermal radiation and heat source. The acquired equations are numerically computed with the aid of Runge Kutta Fehlberg 4–5th order method. The entropy behavior and Bejan number are examined utilizing graphs. The novelty of the work lies in perceiving which shape of nanoparticle has better tendency in escalating the heat transport and whip up the efficiency of the channel. The flow repercussion so obtained are emphasized for both hybrid and nano phase. On enlarging squeezing parameter, velocity escalates whereas for large values of rotating parameter velocity diminishes. The temperature is highest for blade structured and least for brick shaped nanoparticles. Heat generation/absorption parameter plays a crucial role in controlling the heating and cooling process. Higher value of this parameter augments the thermal profile. Bejan number is least for blade structured nanoparticles.

The Influences of Squeezed Inviscid Flow between Parallel Plates

Purpose. The main purpose of this study is to investigate the unsteady flow behavior of second-grade inviscid fluid between parallel plates. The effects on the flow are explored through modeling of continuity, momentum, and energy equations. Graphical and tabular exploration has been made to analyze the impact of several influential variables on the dimensionless temperature and velocity profiles. Three-dimensional graphs and stream lines are also mentioned. Design/Approach/Methodology. The governing equations have been metamorphosed into nonlinear ordinary differential equations by using suitable transformation which is the main focus of the study. To approach the solution of the problem numerically, we have used the numerical method such as shooting technique along with Runge–Kutta method is implemented. Findings. The graphs for the squeezing number, Prandtl number, and Eckert number are decreasing by increasing the values of these parameters. The graphs of skin friction coefficient and Nusselt number are increasing by changing the values of both parameters. Originality/Value. The significances of an unsteady squeezed flow of a nonviscous second-grade fluid between parallel plates by using boundary layer phenomenon are discussed.
