HEAT EXCHANGE MATRIX THE FUNCTION OF A HEAT EXCHANGER IS DEPENDENT UPON THE AREA OF EXPOSURE TO THE FLUIDS IN PROCESS. FINS ARE COMMONLY USED TO INCREASE EXTERNAL SURFACE AREAS. TO EXTEND THE INNER SURFACE OF A TUBE OR VESSEL IS MORE DIFFICULT AND THERE IS CURRENTLY NO COST EFFECTIVE METHOD TO DO SO. THIS REDEARCH IS TO DEVELOP THE USE OF A MATRIX COMPOSED OF SMALL, HOLLOW, METAL CYLINDERS, BRAZED ...

OPERATING STRATEGIES HAVE BEEN DEVELOPED FOR BIOLOGICAL SEQUENCING BATCH REACTOR (SBR) TREATMENT OF BOTH MUNICIPAL WWASTE (I.E. LOW-STRENGTH WASTES) AND INDUSTRIAL WASTES (I.E.HIGH-STRENGTH WASTES CONTAINING DIFFICULT TO DEGRADE ORGANICS). SBR SYSTEMS SHOULD ALSO OFFER ADVANTAGES FOR BIOLOGICAL TREATMENT OF MIXED MUNCIPAL AND INDUSTRIAL WASTEWATERS THAT ARE RELATIVELY LOW STRENGTH, BUT CONTAIN INO ...

Solvents are a valuable processing tool in the chemical and related industries. Solvent are used to enhance mass transfer, heat transfer and in most cases are a processing aid and eventually are not used in the final product but to enhance the fabrication of the final product. While solvents are very valuable, they also cause a significant problem with their volatility and associated emissions. ...

The US Army and Marines rely significantly on fossil-fuel based tactical power generation to provide electrical energy to deployed troops in small camps and forward operation bases. These generators are sized to support the expected maximum power but are often operated far below rated power due to the dynamic nature of electrical loads. On average, the generators are loaded less than 50% of the ...

New enhancements to mobile computers including smaller sensors, displays and powerful processors have made them much more attractive for the battlefield, not only as wearable systems for soldiers, but also unattended ground sensors a warfighter can leave behind for situational awareness. Unfortunately, while the technologies for hands-free interfacing have improved greatly, the challenge of limiti ...

There are many different RF devices used in military networks. It is highly desirable to have scalable networks, where new devices can be readily installed without hardware or software changes elsewhere in the network. It is known that achieving this goal

As infrared (IR) electo-optical sensors improve in both availability and quality a strong need exists to have comparable improvements in the performance of military obscurants within the IR band. Conventional approaches for creating effective IR obscurants have relied primarily on shaped metal particles with high aspect ratios (e.g. rods, flakes). While efficient it is difficult to create very ...

The proposed project will focus on the development of closed loop frequency control hardware and algorithms for control of high quality factor tunable microwave filters based upon evanescent mode resonators. The developed controller will be integrated with a representative filter. As a system demonstration, the integrated filter/controller module will then be applied to a next generation frequency ...

Millimeter-wave RADAR imaging holds significant promise for many applications from rotorcraft DVE mitigation to standoff security screening. A key challenge of this imaging modality, however, has been the implementation of an effective method for creating an image without relying on either mechanical scanning or expensive, high SWAP phased array techniques. Herein, we present a concept for creat ...
