| Outline of Final Research Achievements |
Electrostatic cooling is known as the phenomena of enhancing the cooling or heating effects by application of an electrostatic field, but the physical theory is not well known. Our research is based on this theory that electrostatic cooling disrupting will increase the heat faster from supercooled ice slush, allowing it to solidify rapidly. The purpose of this research was to create a new technology for doing this transition efficiently. First at room temperature we generated a corona wind to investigate the mass transfer effect. I succeeded to measure the effect of heat transfer with this system. At present we are setting this up to test at low temperature environment, and proceeding well.
