Performance of rough secant slider bearing lubricated with couple stress fluid in the presence of magnetic field

Modern Physics Letters B, Journal Year: 2023, Volume and Issue: 38(19)

Published: Dec. 12, 2023

The effect of surface roughness, magnetic field, and couple stress on the performance secant slider bearing is studied in this paper. effectiveness assessed by using a liquid as lubricant process. Because microstructural impacts, fluids have distinctive rheological characteristics. These features potential to make major impact bearing’s performance. novel aspect study that roughness taken into consideration. modified Reynolds equation derived Christensen’s stochastic theory for roughness. Here, both transverse longitudinal patterns are considered. analytical solutions obtained steady-state pressure, load-carrying capacity, film stiffness, damping coefficient. results presented various parameters through graphs tables. combined field significant It noticed increase with parameter, reverse phenomenon observed parameter. When pattern assumed bearing, characteristics like load, stiffness film, coefficient significantly.

Numerical study of stagnation point flow of Casson-Carreau fluid over a continuous moving sheet

AIMS Mathematics, Journal Year: 2023, Volume and Issue: 8(3), P. 7005 - 7020

Published: Jan. 1, 2023

<abstract> <p>This paper is devoted to analysis the behavior of heat transfer Casson-Carreau fluid at magnetohydrodynamic (MHD) stagnation point with thermal radiation over a continuous moving sheet. The suitable similarity transform utilized governing differential equations into system and then solve converted non-linear by collocation technique based on B-spline function (CTBS) Runge-Kutta method (RK). quasi-linearization approach model linear used CTBS acquire solution equations. obtained results are investigated present literature direct comparison. It found that an increment in value Weissenberg number decreases velocity profile enhances temperature for Casson Carreau fluids. Conversely, increasing values magnetic parameter, shrinking parameter improve depreciate distribution. Further, declines improvement Prandtl influence distinct physical parameters profiles depicted via tables illustrative graphs.</p> </abstract>
