Vapor explosion and shock wave generating device, motor, and turbine device

Abstract

Provided is a device which can reliably generate a vapor explosion. A device which can reliably generate a vapor explosion and shock waves is proposed. This device is provided as an experimental means for research and development of a vapor explosion and shock waves, and paves the way for applications to motors or turbines. A high-temperature liquid ( 0102 ) including a molten metal is retained in the inside of a liquid retention container ( 0101 ). Heating devices ( 0103 ) to maintain the high-temperature liquid at a high temperature are provided around the liquid retention container. An inlet ( 0104 ) through which water is intermittently charged is provided in the bottom portion of the liquid retention container, and a pressure-proof valve ( 0105 ) is provided in the inlet so as to close the inlet. The pressure-proof valve closes the inlet using a force of a spring ( 0106 ). However, when the pressure-proof valve is moved upwardly by a timing cam ( 0107 ), water is intermittently charged through a clearance between the valve and the inlet. When the water is intermittently charged to the bottom portion-side high-temperature liquid, an vapor explosion and shock waves occur.
