Numerical Analysis of Mass and Momentum Transfer in Co-Axial Cylinders with Rotating Inner Cylinder
to be necessary. In this paper, the coaxial cylinders with rotating inner cylinder and a non-Newtonian fluid is simulated. Differential equations of mass and momentum transfer with simple problem situation are introduced and the boundary conditions for solving...
Numerical Simualtion of a Non-Newtonian Fluid during the Filling Process of a Die
In this paper, a numerical model is developed which can predict behavior of non-Newtonian fluids....
Theoretical and Experimental Study of the Rheological Behaviour of Non-Newtonian Fluids Using Falling Cylinder Rheometer
The present study attempted to solve falling cylinder governing equation for power law model fluids and also construct a novel falling cylinder rheometer (F.C.R.) to measure the rheological properties of power law model non-Newtonian fluids...
A numerical simulation for solving two dimensional non-Newtonian jet buckling in Moulding Process by VOF method
This work presents a numerical technique for solving two-dimensional non- Newtonian free surface flows.
The governing equations are solved by VOF method on a staggered grid. It uses marker particles to describe the ...
MODELING OF NON-NEWTONIAN FLUID FLOW WITHIN SIMPLEX ATOMIZERS
In this paper the Volume-of-Fluid (VOF) method is used to simulate Newtonian and non-Newtonian fluid flow within simplex (pressure-swirl) atomizers. The two-dimensional axisymmetric swirl Navier-Stokes equations coupled with the VOF method...
In situ rheological characterisation of wastewater sludge: Comparison of stirred bioreactor and pipe flow configurations
In the present work, non-Newtonian properties of activated sludge are investigated using a bench test device specially developed for the purpose of this work. This set-up consists in a bioreactor equipped with a helical ...
Effect of rheological properties change on heat transfer coefficient of Non Newtonian fluid
Researchers try to increase heat transfer coefficient to decrease operation costs. Among different kind of fluids, Non-Newtonian fluids have an important role in industry because of their properties; for example, drilling mud as a Non-Newtonian...
Numerical Study of Hemodynamic Wall Parameters on Pulsatile Flow through Arterial Stenosis
Abstract: In this paper hemodynamic wall parameters which play an important role to diagnose arterial disease were studied and compared for three different rheology models (Newtonian, Power law and Quemada). Also because ...
Homotopy Perturbation Method to Study Flow and Heat Transfer of a Modified Second Grade Fluid over a Porous Plate
for studies
where shear dependent viscosity (shear-thinning and shearthickening)
may happen, and has capability to predict normal
stress differences too that are seen in die-swelling and rodclimbing
behaviors in non-Newtonian fluids...
