“…In the research of the numerical simulation of the fluid-film, firstly the continuous physical fields in spatial domain were replaced, such as the velocity and the pressure fields, with a set of a finite number of variable values at discrete points, and then the algebraic equations about the relationship between these variables field variables at discrete points were established [5]. Finally, these algebraic equations were solved to obtain an approximation of the field variables.…”

Abstract. The gap of the friction pair interface is tiny for the heat pump mechanical seal, the dynamic characteristics of the fluid-film couldn't be come true easily when using the traditional experimental test. In this paper, the 3D FEM model of the fluid-film is set up, and then the dynamic characteristics of the fluid-film were simulated by the computational fluid dynamics (CFD) theory and method, the pressure of the fluid-film were gotten, and the results of the analysis were compared with the theoretical values to get a better agreement. Then based on this model, the impact laws of the differential pressure and the width on the pressure were further studied, the results provide a useful reference for the design of heat pump mechanical seal.

Introduction: Nanofluids, hybrid nanofluid possesses thermophysical features that boost the fluid performance. This research work is motivated by the utilization of water solar collectors that incorporate non-Newtonian, power-law hybrid nanofluid in a three-dimensional model, considering the two-phase model.Method: The primary objective of this study is to transform the governing equations of the flow model into a set of ordinary differential equations by employing the three-parameters group technique. Based on the innovative discoveries, two models incorporating new associated functions have been successfully developed for two distinct scenarios characterized by the power-law index, n. The impact of physical factors on the velocity profile, temperature distribution, concentration field, and entropy output of the system is clearly illustrated through a variety of graphs.Results: The results indicated that the inclination angle of 20° had the best thermal characteristics compared to other inclinations. The entropy generation reached its maximum value at temperature difference of 13 K due to irreversibility of the system, which indicates that the system is more efficient.Discussion: Furthermore, the increasing percentage in Nusselt number is predicted to be 28.18% when the Prandtl number is taken a range. The Sherwood number enhanced up to 18.61% with a range of Brownian motion. A quantitative comparison is conducted between the present results and the literature in order to validate the superior efficiency of the used method.

“…Parmar and Timol [17] developed a generic technique for solving the Rayleigh issue for an MHD Sisko fluid using a one-parameter general group transformation. Using a two-parameter group, Sojoudi et al [18] established an efficient solution for free unstable convection, non-Newtonian fluid flow across a vertical plate moving continuously and exposed to heat flux constantly. For a magnetic nano fluid, the group analysis of its free convection flow with chemical reaction problem was by Uddin et al [19].…”

In this study, the Group Transformation method is employed to simulate the laminar free convection problem involving a viscous incompressible fluid on a vertically oriented cone with a uniform heat flux on its surface. The non-dimensional governing partial differential equations (PDEs) and their boundary conditions are reduced to ordinary differential equations (ODEs) with corresponding appropriate conditions. To solve the resulting non-linear ODEs, the Range-Kutta shooting method is applied. The temperature and velocity fields are graphically presented for various parameters, such as the semi-vertical angle and Prandtl number. Furthermore, the local Nusselt number and skin fraction are analyzed numerically.
