Advanced Thermal and Environmental Concepts, Inc. proposes to utilize electrohydrodynamic (EHD) technology to reduce the amount of frost that forms on cold plates in food freezers. The defrost cycle consumes about 5-15% of the energy to operate an industrial food freezer. During Phase I of our project, we used EHD technology to reduce frost mass by 35% and frost height by as mush as 65% under cert ...

DESCRIPTION (Provided by Applicant): The long-term objective of this proposal is to generate a cartilage product with mechanical properties comparable to those of adult articular cartilage for the repair of focal articular defects. Based on previous experimental findings, our hypothesis is that mechanical loading will improve the growth of tissue engineered cartila ...

The purpose of this Phase II effort is to build a rugged, compact optical phased array for coherent addition of laser beams, a crucial building block for multi-kilowatt continuous wave laser devices. This effort builds on the success of the Phase I effortwhere it was shown that an array of electro-optic waveguides in Potassium Titanyl Phosphate (KTP) could be used for phase control. The low-voltag ...

A comprehensive rigorous unified physical formulation and accurate efficient robust computation technique are described for simulating complex compressible viscous reacting multiphases flow phenomena which can affect or control the performance or signatureof a flight vehicle during al phases of operation. The method is designed to enable continuous seamless predictions for internal, external, and ...

60765 Current designs for electric motors use a housing that acts as both a structural support and as a method of cooling the stator and rotor. This approach to cooling is not as effective as possible because heat must flow from the rotor and stator through the housing to the cooling media. Because the housing must contain the coolant, it is also larger, heavier, and more expensive than n ...

The specific innovation proposed is to design an advanced composite airframe panel for damage tolerance by incorporating biologic solutions to a similar problem found in nature, using a biomimetic approach. We will identify principal material (fiber) directions and density profiles about naturally occurring holes in bones through a microscopic and radiographic techniques. These holes are known to ...

This SBIR Phase1 project will involve the development of a novel method of simultaneously measuring multiple trace chemical species in jet engine exhaust, based upon an extension of the technology of tunable diode laser (TDL) spectroscopy. We will develop and demonstrate a new means of combining the light from two or more diode lasers into a single analysis beam. This will enable a multiplication ...

60520 The atmospheric abundance of carbon dioxide and methane have increased dramatically during the industrial era. Since these increases can perturb the global climate, it is vital to understand and quantify the factors controlling them. This is difficult because CO2 and CH4 have a wide range of complex surface sources and sinks, which have both natural and anthropogenic components. H ...

60921 Although there are large uncertainties in the quantification of aerosol particles, they have important effects on visibility, acid deposition, climate, and human health. Organic compounds, generated from energy related activities, are known to constitute a large fraction of the ambient aerosol mass in many locations. The quantification of these compounds is hindered by the lack of re ...
