Mathematical modeling for laminar flow of power law fluid in porous media. Silva, Renato A. Centro Universitario Norte do Espirito Santo. In this paper, the macroscopic equations for laminar power-law fluid flow is obtained for a porous medium starting from traditional equations Navier-Stokes. Then, the volume averaging is applied in traditional transport equations with the power-law fluid model.

Settling is the process by which particulates settle to the bottom of a liquid and form a sediment. Particles that experience a force, either due to gravity or due to centrifugal motion will tend to move in a uniform manner in the direction exerted by that force. For gravity settling, this means that the particles will tend to fall to the bottom of the vessel, forming a slurry at the vessel base. Settling is an important operation in many applications, such as mining , wastewater treatment, biological science, space propellant reignition, [1] and scooping. For settling particles that are considered individually, i.

Show all documents Fluids are of three types:-Liquid, Semi liquid and Gaseous. The fluid that obeys the Newtonian law of viscosity is called Newtonian fluids and in such case the shear stress is found to be a linear function of rate of strain. Such fluids are Known as non- Newtonian fluids and in these type of fluids strain —stress relationship is non linear. Rivulet flow of generalized Newtonian fluids In the present work we considered steady unidirectional gravity-driven flow of a uniform thin rivulet of a generalized Newtonian fluid down a vertical planar substrate.

Two forces act on a 55 kg object The net force acting on the skier is the sum of forces. The total force is 5 N and is equal to the magnitude of the sum vector of the two forces if we assume that the direction of the force is equal to the direction of the 4. The net force exerted on the car must be. For the greatest force, the two forces must be act in opposite direction such that : So, the magnitude of the other force is

The viscosity of blood obtained by using a rotational viscometer decreases with the time elapsed from the beginning of measurement until it reaches a constant value determined by the magnitude of shear rate. Therefore, we devised a new method by which one can obtain the viscosity of various fluids that are not affected by both the time elapsed from the beginning of measurement and the magnitude of shear rate by considering the balance of the forces acting on a solid spherical particle freely falling in a quiescent viscous fluid. By using the new method, we studied the rheologic behavior of corn syrups, carboxy-methyl cellulose, and human blood; and compared the results with those obtained with a cone-and-plate viscometer. It was found that in the case of corn syrups and washed red cell suspensions in which no red cell aggregate rouleau was formed, the viscosity obtained with the two different methods were almost the same. In contrast to this, in the case of the whole blood in which massive aggregates were formed, the viscosity obtained with a falling-ball viscometer was much larger than that obtained with a cone-plate viscometer.

In this study, xanthan gum is used as a model exopolymer to demonstrate potential effects of non-Newtonian properties of natural aquatic systems on settling dynamics of particles. Rheological measurements combined with settling experiments using visualization methods revealed that instantaneous velocity fluctuations and a flow pattern formed around a particle are the effects of solution viscoelasticity and shear-thinning properties and that the average settling velocity depends on the exopolymer concentration and particle size.
