NUMERICAL MODELING OF SHIP THERMOACOUSTIC LNG REGASIFICATION SYSTEM

Abstract

On the ships with power plants that consume LNG the special systems of regasification are used. In common, the LNG systems for regasification of LNG uses the warmth of outboard water, or coolant of the ships power plants. Liquid natural gas – methane is the source of «cryogenic energy». More often, that «cryogenic» temperature potential of LNG of fuel is not used. There is vital possibility to utilize this potential power with the help of thermoacoustic thermal machines. Thermoacoustic technology can potentially provide opportunities to improve the energy efficiency of EMS through utilization of lowtemperature waste heat resources. In this article the thermoacoustic energy generating system for regasification of cryogenic fuel of EMS LNG tanker was developed. With the help of the program DELTA EC the variant calculations of cryogenic TAE of different powers were conducted. The results of calculations for numeral designs are presented. As a result, the most rational constructions of cryogenic TAE and the tasks for further researches were determined.
