Abstract This paper presents a systematic study of flow and heat transfer mechanisms in compressor disk cavity with an axial throughflow under centrifugal buoyancy-driven convection, comparing previously published experimental data. Wall-modeled large-eddy simulations (WMLES) are conducted for six operating conditions, covering range rotational Reynolds number (3.2×105−2.2×106), buoyancy parame...
In this paper, the unsteady magnetohydrodynamic (MHD) Couette flow of two non-Newtonian immiscible fluids micropolar and dusty (fluid-particle suspension) are considered in horizontal channel with heat transfer. A comprehensive mathematical model computational simulation modified cubic B-Spline-Differential Quadrature method (MCB-DQM) is described for flow. The coupled partial differential equa...
This paper presents a comprehensive analysis of the momentum and energy transfer in compressible turbulent boundary layers based on integral identities. By considering data obtained from direct numerical simulations for wide parameter range, superordinate influences compressibility, wall heat pressure gradient terms governing equations are identified visualized. allows us both to determine what...
This work aims at examining the thermophoresis and Brownian motion characteristics on stagnation point flow of Cross nanofluid over a permeable stretching /contracting surface. Flow equations are modelled by means Buongiorno model. The transformed non-linear fluid transport solved numerically through Runge-Kutta Fehlberg (RKF) approach. temporal stability test is executed to reveal behaviour du...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
Studies of gender-specific variation are often contradictory, depending on the author's implicit assumptions about sex and gender, the methodology, the samples used, etc. Thus, as Eckert and McConnell-Ginet (1992: 90) state, “women's language has been said to reflect their [our] conservativism, prestige consciousness, upward mobility, insecurity, deference, nurture, emotional expressivity, conn...

Profound temperature peaks are observed in regions of high velocity shear in a 2D dusty plasma experiment with laser-driven flow. These are attributed to viscous heating, which occurs due to collisional scattering in a shear flow. Using measurements of viscosity, thermal conductivity, and spatial profiles of flow velocity and temperature, we determine three dimensionless numbers: Brinkman, Br =...
This article numerically investigates the 2D, steady, laminar, incompressible fluid flow, mass and heat transfer of a non-Newtonian model induced by stretching surface. A Casson is considered to study behavior flowing fluid. The magnetic field porous medium are in flow momentum, whereas viscous dissipation also taken into account energy transport phenomena. To see concentration, concentration e...
The objective of the current analysis is to study influence MHD on flow an ethylene glycol-based nanofluid containing copper nanoparticles through a exponential stretching sheet. Several parameters including Dufour, thermal radiation, Magnetohydrodynamic (MHD), and Eckart number, were investigated for their impacts fluid flow, heat mass transfer profiles, convective boundary conditions, while N...
