The Characteristics of Bubbles in a Column Heat Exchanger for the Application of Direct Contact LNG Evaporator
직접접촉식 LNG기화기 응용을 위한 칼럼 열교환기 기포특성에 관한 연구
Abstract
In the present investigation, it has been proposed to utilize a direct contact heat exchanger as an evaporator to solve the difficulties such as scaling, corrosion and law thermal efficiencies, associated with the conventional evaporator. Liquified nitrozen was utilized as a working fluid to investigate basic natures of bubble dynamics in the evaporator, and spray nozzles were adopted to inject liquified nitrozen into the spray column with varying flow rates of dispersed phase fluids. Experimentations were carried out in the range of
