Abstract:
An primary experimental research on the temperature difference between the phases has been performed in the super-sonic steam and liquid two phase flow in the steam inject. As the thermal resistance in the direct contact heat transfer between steam and cool water, there exists obviously the value of temperature difference. It increases with the flow ratio of water to steam, but keeps constant while the flow ratio is greater than a specific value. It reaches its minimum value at a critical mass flow rate. The results are both theoretically and practically valuable.
