Magnetohydrodynamic Fluid

Effects of inclination and free convection on velocity profile for magnetohydrodynamic (MHD) fluid flow in an inclined cylindrical pipe has been investigated. The governing partial differential equations are the equations of continuity, momentum and energy which are converted into ordinary differential equation by employing similarity transformation and solved numerically by the Runge- Kutta fourth order scheme with shooting method. The findings, which are presented in the form of tables and graphs reveal that; when Hartmann number, Grashoff number and Gamma are decreased, the velocity of the fluid increases. The results of the study may be useful for the different model investigations, especially, in various areas of science and technology in which optimal inclination and free convection are utilized.

Vertical Annulus

We have initially investigated the temperature dependence of density and viscosity of a number of crude oils, collected from various hydrocarbon reservoirs in Oman. The measured data are then utilized to investigate the flow dynamics of these hydrocarbon fluids under gravity and applied pressures at various temperatures. We have modeled the flow of the various crude oil samples through a vertical (a) annulus and (b) cylindrical pipe - all treated within the Newtonian fluid flow approximation of a laminar flow - to investigate the flow properties of these samples. A computer program is developed so that the temperature dependence of the fluid flow distinctly separates the laminar mode from a turbulent mode with respect to Reynolds numbers within the ranges Re<2000 and Re>2000. The adopted models of the velocity profiles, mass rate of flow and viscous force on the solid surface are not novel, but the present calculations aim to specifically use the various Omani crude oil samples with various AIP values; the calculated results shed some light on the dynamics of these specific samples within Newtonian approximation. The measured physical properties and the subsequent calculations of the relevant dynamical properties might be useful for various purposes e.g. extraction and transportation of crude oils through pipes.

Magnetohydrodynamic Fluid

The current perusal investigation was carried out for the result of a chemical reaction and Schmidt number on magnetohydrodynamic fluid flow towards a Sphere with Rosseland approximation. The Roseland estimate is utilized to portray the radiative heat transition in the energy condition. The crucial equations of continuity, thermal and solutal boundary layers are reassembled into sets of nonlinear models. The highly nonlinear partial differential models are converted into a nonlinear ordinary differential structure through the proper dimensionless quantities. The numerical arrangements of standard differential structures have been procured by applying the fourth-order Runge-Kutta-Fehlberg strategy with shooting technique through MATHEMATICA software. The quantities of physical interest are graphically presented and discussed in detail. Correlation with past writing results is additionally done and is discovered to be excellent concurrence with those distributed before.
