Visual Experimental Study on Two Phase Flow Patterns of the Evaporative Cooling System

The flow pattern is of great significance for calculating boiling heat transfer and two phase pressure drop, there no uniform diagram the evaporative cooling system. This paper has carried out experimental research on in liquid box surface-mounted system establish a mathematical prediction model transition. results show that patterns are mainly bubble flow, churn misty under different thermal loads. By comparing observed with existing diagrams, it can be found diagrams not suitable division A new proposed based change interfacial area concentration box. good agreement data, which provides valuable insights into paves way further calculation
