A novel steam ejector with pressure regulation to optimize the entrained flow passage for performance improvement in MED-TVC desalination system

Steam ejector plays a critical role in MED-TVC desalination system that can achieve a good balance between freshwater production and energy savings. In this study, a pressure regulation technology is proposed to optimize the entrained flow passage and thus improve the ejector performance. The theore...

520			\|a Steam ejector plays a critical role in MED-TVC desalination system that can achieve a good balance between freshwater production and energy savings. In this study, a pressure regulation technology is proposed to optimize the entrained flow passage and thus improve the ejector performance. The theoretical basis is that there have some existing low-pressure potentials inside the ejector that can be used to alleviate the high-pressure effect and shock wave at the mixing chamber end. Then the feasibility verification and performance comparison of different pressure regulation schemes is implemented systematically. Analysis and research mainly pay attention to the influences of pressure regulations on the mass flow rate, the entrainment ratio and internal flow field. The results reveal that there is an optimum combination of pressure regulation schemes, by which a most considerable entrainment ratio improvement could be achieved, as large as 11.77% within the simulated conditions, and with 3.94% even under the design condition. More specifically, for the given steam ejector, TMCE pressure regulation could be used if the ejector operates under the design condition. For the off-design conditions, CMCE pressure regulation is the best choice if the back pressure is larger than 34 kPa, otherwise DMCE pressure regulation should be chosen.

Analysis and research mainly pay attention to the influences of pressure regulations on the mass flow rate, the entrainment ratio and internal flow field. The results reveal that there is an optimum combination of pressure regulation schemes, by which a most considerable entrainment ratio improvement could be achieved, as large as 11.77% within the simulated conditions, and with 3.94% even under the design condition. More specifically, for the given steam ejector, TMCE pressure regulation could be used if the ejector operates under the design condition. For the off-design conditions, CMCE pressure regulation is the best choice if the back pressure is larger than 34 kPa, otherwise DMCE pressure regulation should be chosen. 1.1\x Energie (DE-2867)14175-2 stw 1.2\x Energieökonomik (DE-2867)18350-4 stw 1.3\x Energietechnik (DE-2867)18353-5 stw 1.4\x Energiemanagement (DE-2867)18349-3 stw 1.5\x Energieforschung (DE-2867)18348-5 stw Pressure regulation Novel steam ejector Entrained flow passage Performance improvement High-pressure effect Flow field Liu, Zhongliang verfasserin aut Shi, Can verfasserin aut Li, Yanxia verfasserin aut Enthalten in Energy Amsterdam [u.a.] : Elsevier Science, 1976 158, Seite 305-316 Online-Ressource (DE-627)320597903 (DE-600)2019804-8 (DE-576)116451815 1873-6785 nnns volume:158 pages:305-316 GBV_USEFLAG_U SYSFLAG_U GBV_ELV GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_31 GBV_ILN_32 GBV_ILN_40 GBV_ILN_60 GBV_ILN_62 GBV_ILN_63 GBV_ILN_65 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_74 GBV_ILN_90 GBV_ILN_95 GBV_ILN_100 GBV_ILN_105 GBV_ILN_110 GBV_ILN_150 GBV_ILN_151 GBV_ILN_224 GBV_ILN_370 GBV_ILN_602 GBV_ILN_702 GBV_ILN_2003 GBV_ILN_2004 GBV_ILN_2005 GBV_ILN_2011 GBV_ILN_2014 GBV_ILN_2015 GBV_ILN_2020 GBV_ILN_2021 GBV_ILN_2025 GBV_ILN_2027 GBV_ILN_2034 GBV_ILN_2038 GBV_ILN_2044 GBV_ILN_2048 GBV_ILN_2049 GBV_ILN_2050 GBV_ILN_2056 GBV_ILN_2059 GBV_ILN_2061 GBV_ILN_2064 GBV_ILN_2065 GBV_ILN_2068 GBV_ILN_2111 GBV_ILN_2112 GBV_ILN_2113 GBV_ILN_2118 GBV_ILN_2122 GBV_ILN_2129 GBV_ILN_2143 GBV_ILN_2147 GBV_ILN_2148 GBV_ILN_2152 GBV_ILN_2153 GBV_ILN_2190 GBV_ILN_2336 GBV_ILN_2507 GBV_ILN_2522 GBV_ILN_4035 GBV_ILN_4037 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4242 GBV_ILN_4251 GBV_ILN_4305 GBV_ILN_4313 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4325 GBV_ILN_4326 GBV_ILN_4333 GBV_ILN_4334 GBV_ILN_4335 GBV_ILN_4338 GBV_ILN_4393 50.70 Energie: Allgemeines AR 158 305-316

In this study, a pressure regulation technology is proposed to optimize the entrained flow passage and thus improve the ejector performance. The theoretical basis is that there have some existing low-pressure potentials inside the ejector that can be used to alleviate the high-pressure effect and shock wave at the mixing chamber end. Then the feasibility verification and performance comparison of different pressure regulation schemes is implemented systematically. Analysis and research mainly pay attention to the influences of pressure regulations on the mass flow rate, the entrainment ratio and internal flow field.

title_auth	A novel steam ejector with pressure regulation to optimize the entrained flow passage for performance improvement in MED-TVC desalination system
abstract	Steam ejector plays a critical role in MED-TVC desalination system that can achieve a good balance between freshwater production and energy savings. In this study, a pressure regulation technology is proposed to optimize the entrained flow passage and thus improve the ejector performance. The theoretical basis is that there have some existing low-pressure potentials inside the ejector that can be used to alleviate the high-pressure effect and shock wave at the mixing chamber end. Then the feasibility verification and performance comparison of different pressure regulation schemes is implemented systematically. Analysis and research mainly pay attention to the influences of pressure regulations on the mass flow rate, the entrainment ratio and internal flow field. The results reveal that there is an optimum combination of pressure regulation schemes, by which a most considerable entrainment ratio improvement could be achieved, as large as 11.77% within the simulated conditions, and with 3.94% even under the design condition. More specifically, for the given steam ejector, TMCE pressure regulation could be used if the ejector operates under the design condition. For the off-design conditions, CMCE pressure regulation is the best choice if the back pressure is larger than 34 kPa, otherwise DMCE pressure regulation should be chosen.
