The main purpose current exploration is to examine the influence of viscous dissipation and nonlinear radiation in three-dimensional (3D) Williamson fluid flow on an exponentially stretching through porous medium with effect activation energy along chemical reaction. By employing suitable transformation, partial equations (PDEs) are transmuted ordinary differential (ODEs) which subsequently solved numerically by using Range-Kutta method shooting technique utilization Matlab script. Characteristics resulting physical parameters appearing modeling like Weissenberg number, Prandtl parameter, porosity Eckert number reaction parameter comprehensively analyzed graphical forms interest providing meaning each parameter. outcomes anticipate that, thermal profile improved increase values due inner heat. enhances strengthening but it has opposite trend number. impact obtained skin friction coefficient, mass heat transfer rates illustrated tables. validity present findings presented comparing them previous investigations.

Lifting and drainage of Sisko fluid film with surface tension: A theoretical study on stationary points and thickness of uniform film

International Journal of Modern Physics B, Journal Year: 2023, Volume and Issue: 37(26)

Published: July 27, 2023

This paper accords with the theoretical study of lifting and drainage Sisko fluid film on a vertically upward moving cylinder surface tension. The flow is induced by motion cylinder, gravity tension gradient. resulting nonlinear ordinary differential equation solved for series form solution making use Adomian decomposition method (ADM). Expressions variables like velocity, volume rate, shear stress are derived. Positions stationary points thickness uniform computed numerically in MATHEMATICA. inverse capillary number C, Stokes [Formula: see text], parameter text] behavior index n emerged as control parameters. showed that positions relocate towards increase C while their fluid–air interface increasing n. Thickness decreases when values increased whilst it increases Analogy between Newtonian fluid’s thinning thickening behaviors points, also made.

Abstract The present research theoretically analyzes the impact of magnetohydrodynamics (MHD) and viscosity variation on couple stress squeeze film properties a cylinder rough planar surface. generalized stochastic Reynolds flow equation is derived by utilizing Stokes theory Christensen's model. solutions for pressure, load-carrying capability, time longitudinal transverse roughness patterns are illustrated graphically to examine impacts MHD, stress, factors. results reveal that, in comparison with smooth case, one-dimensional (transverse) pattern decreases (enhances) time, capability. numerical comparative between Sreekala et al. (Lect Notes Electr Eng 928:765–774, 2023) analysis current performed found excellent agreement.
