Abstract Magnetic field is often applied to stabilize the flow in real life applications of fluid mechanics problems. In present work, it employed a horizontal uniform magnetic regularize triggered due rotating disk. The energy equation also studied subjected such field. different from well-known external vertical It shown that leads similarity system equations with help traditional von Kármán transformations. effects on development velocity and temperature fields are then numerically...

Purpose The purpose of this study is two-fold. First, it aims to differentiate the response a stretching jet encountering quadratic air resistance from classical shape formed in frictionless medium. Second, investigates how resulting forms with and without resistance, seeking evidence that supports similarity flows frequently studied for stretching/moving thin bodies under boundary layer approximation. Design/methodology/approach This extends established electrohydrodynamic theory, used...

This paper is devoted to the study of heat and mass transfer characteristics some nanofluid flows past an infinite flat plate moving vertically. Some water-based nanofluids containing copper (Cu), silver (Ag), oxide (CuO), alumina (Al2O3), titanium (TiO2) are analytically analyzed taking into consideration thermal radiation effect for two types temperature boundary conditions. The physically significant properties like skin friction coefficient Nusselt number easy conceive from derived exact...

The object of this study is the development fluid flow and resultant heat transfer caused by a rotating disk moving vertically upward or downward during an unsteady motion. problem formulated such that similarity equations governing physical phenomenon eventually reduced to those reported in traditional viscous pumping von Karman for motionless but still disk. non-rotating with motion leads formation two-dimensional over Otherwise, rotation vertical action sets up three-dimensional surface....

An exact solution for the steady state Navier-Stokes equations in cylindrical coordinates is presented this work. It serves to investigate fluid flow and heat transfer occurring between two stretchable disks rotating co-axially at constant distance apart. The governing of motion energy are first transformed into a set nonlinear differential equation system by use von Karman similarity transformations, which later solved numerically. small Reynolds number case allows us extract closed-form...

A rapid and effective way of working out the optimum parameter convergence control in homotopy analysis method (HAM) is introduced this paper. As compared with already known ways evaluating HAM either through classical h-level curves h being or from squared residual formula as adopted society, an elegant calculating yielding same values offered. In most cases, new shown to perform quicker better against error when integrations are much harder evaluate even by numerical means. Examples...
