The relationship between heavy rain (HR) and/or strong wind (SW) events and cyclones is investigated for the Balearic Islands. First, a list of HR and SW events is crossreferenced with an objective cyclone database for a 9-year period (from June 1995 to May 2004). The presence of a cyclone centre close to the Balearics is looked for each event. For HR events in most of the cases a cyclone centr...

The prediction of emission concentrations from cyclone collectors is integral to the permitting of agricultural facilities including cotton gins. One method for predicting emission concentrations utilizes fractional efficiency curves. Fractional efficiency curves (FEC’s) were developed for 1D2D, 1D3D, and 2D2D cyclone designs. The procedure used to develop these new FEC’s incorporated log-norma...

Dense medium coal processing technology has been widely used in coal preparation industries in the world since it is the most accurate and efficient coal preparation process to obtain clean coal with a highest possible yield. Separation of coal and impurities using this technology is based on density differences. In literature, a number of mathematical models exist for dense medium cyclones. On...

Recent research to increase understanding, and techniques to improve forecasts, of the structure and structural changes of a tropical cyclone due to interaction with the environment are summarized. The atmospheric environment is considered here, and the oceanic, and air-sea interface environments are summarized in Topic 1.3. Progress in understanding how a tropical cyclone interacts with its en...

Interdisciplinary observations of mesoscale eddies were made to the west of the island of Hawai’i. A central goal of the studies is to improve our understanding of the coupling of physical, biological, and biogeochemical processes that occur within these eddies. A specific objective was to test the hypothesis that the physical mechanisms of mesoscale eddies result in increases in nutrient avail...

• Novel Ionic Liquid that is not corrosive to aluminum used as liquid desiccant. New three-fluid fin-tube desiccant contactor fabricated using aluminum. Experimental performance of the IL solution investigated. The fin–tube showed superior than packed bed contactor. Lower flow rates and pumping power expected experimental a new novel ionic investigated compared with those an adiabatic LiCl for ...

The results of performance testing of four different cyclone designs are included in this paper. The 1D3D, 2D2D, 1D2D and Barrel cyclone designs are typically used to abate particulate matter (PM) emitted by cotton gins. The PM used for testing included three types of cotton gin trash (with and without lint fiber) and fly ash. The performance tests were conducted at different total trash inlet ...

The overall project goal is to assess the skill of the probabilistic nature of mediumand extended-range forecasts of tropical cyclone activity and track over the tropical WPAC. Skill is examined with respect to processes associated with forcing by various tropical circulation factors, which are hypothesized to be the largest contributor to low-frequency variation in tropical cyclone activity an...

In present study, a three-step multi-objective optimization algorithm of cyclone separators is catered for the design objectives. First, the pressure drop (Dp) and collection efficiency (h) in a set of cyclone separators are numerically evaluated. Secondly, two meta models based on the evolved Group Method of Data Handling (GMDH) type neural networks are regarded to model the Dp and h as the re...

The improvement of an innovative dual membrane contactor process for treatment of combined hygiene and metabolic wastewater was investigated. Flux and solute rejection in the combined direct osmosis/osmotic distillation (DO/OD) process were enhanced by incorporating membrane distillation (MD) concepts into the process. Two new configurations were investigated: DO/MD, in which the driving force was
