Thermoacoustic Carbon Nanotube Sound Projectors with Enhanced Efficiency and Broad-band Acoustic Spectra
Abstract
AbstractWe propose to develop an encapsulated thermoacoustic (TA) projector filled with fluid possessingadditional functionalitie"s: adjust the acoustical impedance of TA projector with external water,improve heat dissipation issues, and enhance the overall ene"rgy conversion efficiency. To optimizethe signal processing conditions for improved heat dissipation from interior of the TA projec"tor,we propose a short pulse excitation of thermoacoustic heater. We will study the TA response todifferent signal shape, duty cyc""le, and number of pulses per period for optimal thermalmanagement of the device. The main focus of first year of the proposed progr""am (FY17-FY20)will be on the search for alternative materials with lower heat capacitance per square, a higher heatexchange coeffi""cient, along with mechanical robustness and chemical stability."" - -
