Straight vegetable oils provide cleaner burning and renewable alternatives to diesel fuel, but their inherently high viscosity compared to petroleum based diesel is undesirable for diesel engines. Lowering the viscosity can be simply achieved by eith

A property of biodiesel that currently limits its use to blends of 20% or less is its relatively poor low-temperature properties. Alkoxylation of the unsaturated portion of biodiesel offers the potential benefit of reduced cloud point without comprom

The pyrolysis of Loy Yang coal was investigated under rapid heating conditions in a fluidised bed with a feed rate of 10g/h. Nitrogen was used as the fluidising gas operating at fives times the minimum fluidising velocity. The yields of tar, total vo

A continuous flow rheometer based on the principles of helical flow has been developed for measuring the rheological properties of settling slurries. A special feature of the rheometer is its method for data analysis that allows the fundamental rheol

Mineral solids are usually processed, produced or handled in the form of two-phase slurries. Accurate and reliable measurements of the rheological properties of settling slurries using conventional viscometric instruments can be difficult, if not imp

Most concentrated colloidal suspensions such as cement, drilling fluids, paints, muds, etc., have been considered until now thixotropic fluids with a flow curve of an ideal yield stress fluid. We start by showing from inclined plane tests, intended t

Development of more effective technologies of utilising low rank coals for power generation has been driven by a demand for higher efficiency, low capital costs and minimal environmental impacts. Fluidised bed systems are regarded as one of the more

A minimum principle, which has been derived for the steady, creeping flows of a yield stress fluid with shear-dependent viscosity, is extended to flows when the yield stress is also shear dependent, and the flow may be unsteady. As an application of

Summary The effect of the thermal history on the waxy structure of two statically cooled waxy crude oils is examined using a controlled stress rheometer for rheological measurements and a microscope to observe microstructure of wax crystals. A three-
