In this research, the rheological properties of non-Newtonian shear thickening fluid (STF) composed nano-sized solid particles have been investigated. The best conditions determined by optimizing both experimental production method and measurement system STFs. Mechanical, ultrasonic, mechanical ultrasonic mixing methods were used in STFs that silica particle (solid: aerosil) polyethylene glycol...

Nowadays a wide variety of different accessories used in combination with rotational rheomters are available. Such techniques range from rheo-optical methods to applying external pressures and electrical or magnetical fields. In addition systems transforming the rotational movement of the rheometer allow investigations on extensional rheology or tribology with a rheometer. INTRODUCTION Rheologi...

A non-Newtonian fluid is a fluid whose flow properties differ in many ways from those of Newtonian fluids. Most commonly the viscosity of non-Newtonian fluids is not independent of shear rate or shear rate history. In practice, many fluid materials exhibits non-Newtonian fluid behavior such as: salt solutions, molten, ketchup, custard, toothpaste, starch suspensions, paint, blood, and shampoo e...

Rheological measurements of suspensions are often performed using a rotational rheometer. In this type of rheometer, the tested fluid is sheared between two surfaces, one of which is rotating to generate a laminar flow of the fluid between the surfaces (i.e., a Couette flow). Manufacturers of commercially available rheometers generally recommend the use of a standard oil of known viscosity to v...
