A REVIEW OF GEYSERING FLOWS

摘要

This paper reviews geysering theories developed by some previous investigators. The review covers natural geysers and geysering phenomena in engineering equipment. Important aspects with regard to flow processes are discussed, such as boiling, flashing, geometry, and heat transfer mode along the channel. The mechanism of CO_2-driven geysering wells is summarized, based on measurements at Te Aroha, New Zealand. This study shows that neither a heat source nor chambers in the flow passage are necessary to produce a geysering flow.
