INVESTIGATION USE OF FEATURES OF PULSE BIDIRECTIONAL TURBINE IN THERMOACOUSTIC HEAT MACHINES
Abstract
Creating effective use of low temperature heat sources is an important task for the energy, industry, transport. Improving the thermal engine causes permanent reduction of the temperature level of waste heat. The introduction of LNG fuels adds so-called «cryogenic» thermal resources, system of regasification of LNG. Thermoacoustic technology in potentially able to provide the possibility of use of low temperature waste heat resources. Implementation of these technologies prevents the serious problem of direct production of electric energy from the thermoacoustic engine. Using piezoelectric transducer and linear electric generators increases the cost of such systems, create limits of their capacity, and degrades reliability. The introduction of bidirectional impulse turbines should help solve the problem. With pro-gram DELTA EC conducted variant calculations thermoacoustic engine (TAD) with the cycle of Brighton. As a result TAD design has been optimized for use bidirectional impulse turbines. In this work the parameters of BIT sample questionnaire, provided a description of the experimental stand, given the results of experimental studies of mental-identified areas for further work.
