【摘要】 针对分液冷凝换热器的气液分离流动过程,建立了稳定流动情况下的一维数学模型。模型综合考虑了静压,重力,表面张力,切应力,孔径和孔数的影响。考察了在稳定状态下孔径,孔数及其组合方式对气液分离的影响。同时还考察了入口干度和流量对气液分离的影响。发现孔径和孔数对气液分离的影响基本相同,但是干度和流量的影响却是相反的。更多还原

【Abstract】 A mathematical model has set up to investigate the steady state of liquid vapor separation process.The model includes the contributions of static pressure,gravitational force,surface tension,shear stresses,orifice diameter and number.The separation performance was researched under different orifice diameter,number,their combination,inlet quality and flow rate.The results show that orifice diameter and number have similar effect on performance while inlet flow rate and quality have opposite effect.更多还原
