Atomization of viscous and non-newtonian liquids by a.

The non-Newtonian behaviour was modelled by means of a generalized Newtonian constitutive equation using a modified power law viscosity function. A shear-thinning liquid shows its lowered viscosity during the droplets collision by a larger maximum diameter.

Examples of non-Newtonian fluids include molten polymer, aqueous polymer solutions, scurries, coal-water mixture, tomato ketchup, soup, mayonnaise, purees, suspension of small particles, blood, etc. Because non-Newtonian fluids are nonlinear in nature, these are seldom amenable to analysis by classical mathematical techniques.

Measuring Fluid Viscosity and Effects of Shear. - UK Essays.

You can probably guess that non-Newtonian fluids are the opposite of Newtonian fluids. When shear is applied to non-Newtonian fluids, the viscosity of the fluid changes. The behavior of the fluid can be described one of four ways: Dilatant - Viscosity of the fluid increases when shear is applied.Non-newtonian fluid. A fluid that departs from the classic linear newtonian relation between stress and shear rate. In a strict sense, a fluid is any state of matter that is not a solid, and a solid is a state of matter that has a unique stress-free state.Non-Newtonian fluids are broadly defined as any fluid that is not Newtonian. For this laboratory, two types of non-Newtonian fluids will be considered: shear-thickening and shear thinning. Shear-thinning fluids are characterized by a decrease in viscosity as the rate of shear increases.


Similar to an analysis essay, an explication essay examines sentences, verses or passages pulled from longer literary works, to interpret and explain on a detailed level. These mini-essays, typically a single page or less, require a close reading of the text to perform a proper interpretation of the quotation. The.The second-law analysis is applied to a gravity-driven, laminar, non-Newtonian liquid film with free and adiabatic surface. The heat generation by viscous dissipation is included in the analysis. Analytical expressions for velocity and temperature within the film are provided as a function of the flow behaviour index and the Brinkman number.

A non-newtonian is a liquid and solid at the same time.If you work with it quickly then it will be a solid,work with it slow and then you will have the opposite results-liquid.

Viscosity of the non-Newtonian liquids changes with shear rate. Apparent viscosity of such liquids is specified. Some of them show shear-thinning behavior with their viscosity decreasing with increasing shear rate. Others have viscosity that increases with an increase in shear rate, a characteristic called shear thickening.

Newtonian fluids are the simplest mathematical models of fluids that account for viscosity. While no real fluid fits the definition perfectly, many common liquids and gases, such as water and air, can be assumed to be Newtonian for practical calculations under ordinary conditions.

A linearized stability analysis shows that non-Newtonian liquid sheets have a higher growth rate than Newtonian liquid sheets for both symmetric and antisymmetric disturbances, indicating that non-Newtonian liquid sheets are more unstable than Newtonian liquid sheets.

Fractional Walter’s Liquid Model-B has been used in this work to study the combined analysis of heat and mass transfer together with magnetohydrodynamic (MHD) flow over a vertically oscillating plate embedded in a porous medium. A newly defined approach of Caputo-Fabrizio fractional derivative (CFFD) has been used in the mathematical formulation of the problem.

There are two types of shear thickening behavior in the fluid behavior. First, Shear thickening is a non-Newtonian flow behavior (dilatant) observed as an increase in viscosity with increasing shear rate or applied stress also known as time independent material (Barnes, 1989; Maranzano and Wagner, 2001; Lee and Wagner, 2003).

Non-Newtonian effects appear at the third order of the analysis even though the Giesekus-Tanner theorem is not valid. The relative contributions of the elastic and shear rate dependent viscosity characteristics of the liquid to the non-Newtonian behavior are investigated through a parametric study, together with the dependence of the Nusselt number on the nonlinear properties of the fluid.
