Heat exchangers are a used in a commercial, residential, and military cooling systems. Their thermal performance is measured by their ability to efficiently transfer heat. By increasing the heat exchanger efficiency, the size and weight of the system can be reduced. This work explores the use of twisted tape technologies and the use of advanced nanofluids for improving thermal performance. ACT ...

Determining the hazard classification of new propellant formulations is important for transportation safety and storage concerns. To avoid costly grain redesign and additional testing, a model that adequately predicts the shock sensitivity, including the outcome of the Naval Ordnance Laboratory Large Scale Gap Test, of modern solid propellants is required. The goals of this proposal are to de ...

Based on the successful result of the developed micro-FID that was achieved in the Phase I, we propose to integrate a micro-gas analyzer and an optimized micro-FID to obtain the highest signal to noise ratio with a minimum usage of hydrogen for a portable

Fine grained BST ceramics with high density has attractive properties including nonlinearity, low dielectric loss and high dielectric breakdown strength to realize high tunability. In Phase I program we demonstrated that modification of powder characteristics and composition in nano BST powder resulted in greater than 65% tunability at 250KV/cm with ~500KV/cm breakdown strength and Q value greate ...

In the Phase I program, we will design an experiment/test article, and test/validate instrumentation and diagnostics, to be used to obtain plasma properties about a hypersonic vehicle having characteristics and features of the RAM-C flight vehicle. The test model is to be installed and tested in the LENS-XX facility (in Phase II) and experimental planning will be supported by detailed numerical si ...

Aircraft often are subject to externally generated electromagnetic interference (EMI) comprising high intensity radiated fields of strengths in excess of 1000 V/m generated by radars operating at 400 MHz and above. They also are subject to generally less intense fields produced by internal sources such as handheld radios. This EMI may adversely affect the aircraft’s communication, navigation, an ...

Discovery Machine, Inc. (DMI) is partnered with Pennsylvania State University and SAIC (the DMI team) to produce a best practices capture system that goes beyond the storage and dissemination of lessons learned. The proposed system will leverage warfighters’ specific knowledge as deployable knowledge assets. These knowledge assets will be executable best practices that can be embedded in job ...

Present thermoelectric devices operate at about 10% of the Carnot efficiency, whereas the efficiency of compressor-based refrigerators is larger than 30%. An increase in the thermoelectric figure of merit ZT above 3 is needed before thermoelectric technology can replace current air conditioning technologies in many applications. Recent models have predicted that ZT can reach 6 in metal/HgCdTe supe ...

The capability to reliably and remotely detect, identify and track biological aerosols is a critical need for the United States military. EPIR Technologies proposes to improve this capability by making use of the infrared signatures from biological aerosol broadband Mie scattering, comprising both mid and long wavelength infrared (MW/LWIR) components, as well as a potential polarization component. ...

To satisfy DOD's Joint Services needs for the detection and identification of chemical and biological warfare agents, we propose a compact, low-cost sensor system based on the integration of HgCdTe infrared emitter and photodiode detection technologies wi
