Energy Harvesting from Thermal and Vibration Loads due to High Temperature, High Speed Impinging Jets Navy SBIR FY2010.1 Sol No.: Navy SBIR FY2010.1 Topic No.: N101-093 Topic Title: Energy Harvesting from Thermal and Vibration Loads due to High Temperature, High Speed Impinging Jets Proposal No.: N101-093-0100 Firm: Beck Engineering 1490 Lumsden Road Port Orchard, Washington 98367-9179 Contact: Douglas Beck Phone: (360) 876-9710 Abstract: The Navy needs technology to convert the energy content of high-speed impinging jets on aircraft carrier flight decks into useful power. We propose to develop an Active Heat Spreader (AHS) to meet Navy needs. DARPA is developing heat spreaders to remove the concentrated energy from impinging jets on Navy flight decks. Our AHS removes the concentrated energy and uses the removed energy to generate power. Our AHS uses the generated power to enhance the performance of our AHS and make our AHS more durable and reliable and less expensive than competing heat spreaders. In Phase I, we will: develop numerical models and codes to predict and evaluate the performance of our AHS subjected to the impingement of an unsteady hot jet; and conduct laboratory-scale experiments to verify our models and codes. In Phase II, we will design, build, and demonstrate the ability of our AHS to remove concentrated energy from high-speed impinging jets. In Phase III, we will: transition our models and codes into a user-friendly predictive software package; develop an AHS suitable for a real deck environment; and market our software and AHS for many applications in the government and private sector. Benefits: Our Active Heat Spreader (AHS) enables active cooling technology to be used with a passive system, so our AHS can absorb high heat fluxes that will be encountered during take-off and landing of the F-35B. The inability to remove high heat fluxes from computer chips is limiting the achievable performance of computer chips. Our AHS will remove high heat fluxes from computer chips, so chips with higher performances can be included in personal computers, notebook computers, etc. There are many electronics-cooling applications in the government and private sector that could benefit from our AHS, which absorbs higher heat fluxes than state-of-the-art CPLs. There are many hot-section components in gas-turbine engines for military and commercial aircraft and power generation that could benefit from our AHS. Our AHS would remove high heat fluxes from the hot-section components, so less (or none) compressor-bleed air would be required for cooling purposes, which would increase cycle efficiency. Return
