In-situ electrical heating technologies are among the most recent technologies used for bitumen recovery from tar sand and oil shale. These technologies have limited environmental impact because there is little disturbance of the land, and water and solvents are not used. Two-phase ... 詳細を見る

Glow corona discharges are generated from tall objects during thunderstorms previous to a lightning strike. These discharges generate space charge which can hinder the development of subsequent discharges. In order to quantify the shielding effect of positive glow corona, a transient, ... 詳細を見る

Combustion instability has been a serious issue through the developmental history of gas turbine augmentors. When heat release rate oscillations occur in phase with resonant chamber acoustic modes, a feedback cycle is formed in which the strength of local heat release rate and chamber ... 詳細を見る

Polishing is one of the oldest finishing processes. However, exposure to emissions of crystalline silica dust is high. Some toxicological studies have identified this pollutant as responsible for a particular type of lung cancer, silicosis. Operational solutions are needed for reducing ... 詳細を見る

Many materials require functionally graded cellular microstructures whose porosity is engineered to meet specific requirements of diverse applications. It has been shown in previous work that the bubble growth rate of a polymeric foam can be influenced by the surrounding acoustic ... 詳細を見る

This paper presents a novel design of multi-disks Magnetorheological braking system (MR brake) for automotive application. Magnetic saturation in both electromagnetic core and MR fluid is considered in this paper. The electromagnetic analysis of the proposed configuration is carried out ... 詳細を見る

In the field of assessment methodologies, particular importance is given to Non-Destructive Testing Techniques, which aspire to achieve the highest number of information about materials and structures without altering their condition. Ultrasonic Testing exploits the transmission and ... 詳細を見る

Although microwave heating has been studied in great detail, microwave combination heating has not. This work investigated this in a novel microwave combination system that heats the sample through a combination of microwaves and hot air. The study used a coupled electromagnetics ... 詳細を見る

High temperature polymer electrolyte membrane fuel cells (HT PEMFCs) are very promising technologies when used in combined cooling and heating power (CCHP) systems. They are operated at 160°C, offering the possibility of high tolerance to fuel impurities and a possibility to use the heat ... 詳細を見る

With their small size, low manufacturing cost, fast transient response, and capacity to generate fluid power directly from small electrical power sources, microdevices incorporating electroosmostic flow (EOF) have wide-ranging applications, including newly developed high-performance ... 詳細を見る
