  • Serial experiments were conducted to obtain the flow and heat transfer characteristics of boiling two-phase pipe flow under different diameters and side load.By analyzing the measured parameters such as pressure drop,Reynolds number,void fraction,heat flux and heat transfer coefficient in the test pipe,the effects of side load and pipe diameter on the characteristics of boiling two-phase flow were studied.The results show that the greater the side load,the higher the pressure drop,the heat dissipation,and the lower the flow rate,the void fraction and the heat flux.Dynamic load increases the heat transfer coefficient for single-phase water flow.However for boiling two-phase flow,with the increase in side load,the heat transfer coefficient decreases somewhat first,then increases and finally decreases again.Pipe diameter also has great influence on Reynolds number,pressure drop,void fraction and heat dissipation.The pipe with smaller diameter has a larger flow resistance,and good heat exchange ability.
