We investigate the sedimentation of a sphere in a viscoelastic fluid with a cross-shear flow by numerical simulation. The non-Newtonian properties of the suspending fluid determine the settling rate of the sphere. Experiments [Tonmukayakul et al., US

A uniaxial compression apparatus designed to investigate the dynamics of proppant particle packing is described. This dynamic compression device (DCD) uses a small charge of particles, approximately 3.5–7 cm3 depending upon the configuration of an

The cone and plate method is used to quantify the effect of shearing rate, shearing time, and molten alloy temperature on the rheological properties of strontium modified and unmodified near eutectic Al-Si alloys. It is found that in the temperature

A rotating vane-cup rheometer is used to determine the rheological properties of semi-solid slurries, and a procedure is established for characterizing the rheology with emphasis given to the proper and self-consistent evaluation of the material cons

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

Recently, interest in using produced water for hydraulic stimulation processes has greatly increased within the oilfield services industry. However, successful hydraulic fracturing operations using produced water have yet to reach their full potentia

In oil and gas production and transportation a major concern is the formation of gas hydrates (crystalline gas‐water inclusion compounds that are stable at high pressures and low temperatures). Gas hydrates have a tenacious ability to plug pipeline

In completion of oil and gas wells, zonal isolation requires proper cement placement with adequate bonding to the casing and formation. To achieve a successful cementing operation, the cement slurry should be properly designed to enable effective dis
