This paper presents a method to control and direct a physically-based fluid simulation with user defined strokes. Strokes are interpreted as flowlines and introduce a smooth velocity field in their vicinity that allows the fluid simulation to be easily directed by an animator. We also allow the fluid to interact with arbitrarily shaped obstacles and have variable viscosity during the simulation...

Dynamics of stationary axisymmetric configuration of the viscous accreting fluids surrounding a non-rotating compact object in final stages of accretion flow is presented here. For the special case of thin disk approximation, the relativistic fluid equations ignoring self-gravity of the disk are derived in Schwarzschild geometry. For two different state equations, two sets of self-consistent an...

Maybe viscosity in drilling fluid is the most important parameter because cutting removal from well are task of viscose fluid. If viscosity of fluid is less than particular value, cutting will settle down in well and drilling operation will be stopped. In this study, synthesis of Alumina/Polyacrylamide nanocomposite through solution polymerization method was performed. Rheological behavior of m...

drilling fluid is the most important lifeline of the drilling operation, that main task is facilitate the cuttings removal of the drilling. there are varieties of drilling fluids such as sodium bentonite based-drilling fluid is called “mud” and drilling foam or surfactant based-drilling fluid is called “soap”. the present work aims are study on the modified drilling mud properties by using the ...

A sequential implicit numerical scheme is proposed for a system of partial differential equations defining the transport of heat and mass in the channel flow of a variable-viscosity fluid. By adopting the backward difference scheme for time derivative and the central difference scheme for the spatial derivatives, an implicit finite difference scheme is formulated. The variable-coefficient diffu...

In this paper, the measurement of the viscosity of ZnO in ethylene glycol, propylene glycol, mixture of ethylene glycol and water (60:40 by weight), and a mixture of propylene glycol and water (60:40 by weight) and the thermal conductivity in ethylene glycol and propylene glycol as base fluids in the range of temperature from 25 ºC to 60 ºC are investigated. The results indicate that as the tem...

In this study, the natural convection heat transfer of variable properties Al2O3-EG-water nanofluid in a differentially heated rectangular cavity has been investigated numerically. The governing equations, for a Newtonian fluid, have been solved numerically with a finite volume approach. The influences of the pertinent parameters such as Ra in the range of 103-107 and volume fraction of nanopar...

The study consisted of 18 dogs divided into Three groups. Each group consisted of Six dogs with elbow, hip and stifle joint disorders respectively. All the dogs were subjected to synovial fluid evaluation. The physico-chemical parameters recorded in these dogs included synovial fluid volume, color, viscosity, transparency, protein concentration, total nucleated cell count and differential cell ...

Some Bianchi type I viscous fluid cosmological models with a variable cosmological constant are investigated in which the expansion is considered only in two direction i.e. one of the Hubble parameter (H1 = A4 A ) is zero. The viscosity coefficient of bulk viscous fluid is assumed to be a power function of mass density whereas the coefficient of shear viscosity is considered as constant in firs...
