Abstract:

Studies were conducted in the laboratory to investigate how the addition of a insecticides to two sources of Colorado River water would effect the pH of spray mixtures. In addition, we were curious what the effects of various labeled concentrations of buffers, acidifiers, spreader/stickers, and foliar nutrient sprays would have on the pH of spray water. Results showed that in most cases, spray concentration remained alkaline following addition of insecticides and adjuvants, with variations occurring primarily for the OPs. Buffering agents dramatically lowed pH at concentration greater than 0.2

Abstract:

In many industrial fluidized bed reactors, for example fluid catalytic cracking units, coaters and fluid cokers, the reactant feed is introduced into the system in the form of a gas jet or spray for different purposes. A good understanding of the interaction between the feed injection and the bed can lead to improved reactor design and operation. Despite the fact that numerical models and simulations have been used extensively to investigate fluidization processes, still little is known about the interactions of the jet/spray with fluidized beds.

Abstract:

The study in formation and evolution of sprays is essential for developing more detailed physical models and new injection strategies for direct injection internal combustion engines. In the present work, the sprays from a multi-hole injector are evaluated in an effort to characterize the effects of the spray development in a constant surrounding air flow. These interactions are studied in terms of the air turbulence characteristics, the inlet air mass flow and the fuel injection pressure. Ethanol sprays are injected in a constant-flow chamber.

Nowadays the development of new Internal Combustion Engines is mainly driven by the need to reduce tailpipe emissions of pollutants, Green-House Gases and avoid the fossil fuels wasting. The design of dimension and shape of the combustion chamber together with the implementation of different injection strategies e.g., injection timing, spray targeting, higher injection pressure, play a key role in the accomplishment of the aforementioned targets. As far as the match between the fuel injection and evaporation and the combustion chamber shape is concerned, the assessment of the interaction betwe

Abstract:

The degree of connectivity and proximity that results from the configuration of land uses and associated transport networks is an important concept in much of the transportation research agenda. A substantial body of work has developed around the idea that compact, mixed-use development with multimodal transport options will shape travel behavior, increasing the use of transit, walking, and cycling for routine travel. Yet empirical evidence is somewhat mixed. One of the reasons for this uncertainty is the difficulty of defining and measuring sprawl in a meaningful way for use in quantitati

[EN] The potential of diesel engines in terms of robustness, efficiency and energy density has made them widely used as power generators and propulsion systems. Specifically, fuel atomization, vaporization and air-fuel mixing, have a fundamental effect on the combustion process, and consequently, a direct impact on pollutant formation, fuel consumption and noise emission. Since the combustion chamber has a limited space respect to the spray penetration, wall impingement is considered to be a common event in direct injection diesel engines, having a relevant influence in the spray evolution and
