Two‐phase Sakiadis flow of a nanoliquid with nonlinear Boussinesq approximation and Brownian motion past a vertical plate: Koo‐Kleinstreuer‐Li model

Abstract

This paper investigates the Sakiadis flow of a Al2O3‐H2O nanoliquid with consistently scattered dust particles over a vertical plate. To account for the effect of the Brownian movement, the Koo‐Kleinstreuer‐Li model is considered. In some thermal systems such as reactor safety areas, and solar collectors, combustion works from moderate to high temperature, making the relationship between the temperature and density nonlinear. To consider this temperature‐dependent density, the nonlinear Boussinesq estimation is utilized. The present physical structure, which includes energy and momentum equations, is converted into a system of ordinary, coupled, and nonlinear differential conditions through the help of similarity transformations. By using the finite difference code, the subsequent equations have been numerically solved. The impact on the velocity and the thermal profiles of the nondimensional parameters is visualized through graphs. Both the Nusselt number and friction factor strengthen with a higher nonlinear thermal parameter in the case of nonlinear Boussinesq approximation compared to the linear Boussinesq case. Growing estimations of nonlinear thermal parameter deteriorate the thermal profile but it boosts the velocity profile of both liquid and dust phases.

Entropy generation optimization of unsteady radiative hybrid nanofluid flow over a slippery spinning disk

“…Related kinds of literature are in. [14][15][16][17][18][19][20][21][22][23][24] Nanofluid flow involving a rotating disk extends the field of application in numerous technological issues starting from centrifugal machinery, rotational viscometer, pumping of liquid metal at the inflated melting point, computer disk, turbomachinery, and aerospace engineering, which are some examples of its high-level application. [25][26] Von Karman 27 was the initial contributor to deal with such an incompressible steady flow over the spinning disk using the integral method.…”
