The simulation data for the ejector were validated with experimental data. The simulations show that an increase in primary flow superheat will increase the entrainment ratio, while an increase in secondary flow superheat will decrease the entrainment ratio. The output fluid superheat has little effect on the entrainment ratio. As the primary flow superheat increases from 0 to 20 K, the starting position of non-equilibrium condensation moves backward by 5 mm, and the mass fraction of condensed droplets decreases by 20%. The higher the secondary flow superheat, the lower the mass fraction of liquid in the diffusion chamber. The superheat level of the output fluid has no influence on the non-equilibrium condensation phenomenon of the ejector.<\/jats:p>","DOI":"10.3390\/e24070960","type":"journal-article","created":{"date-parts":[[2022,7,11]],"date-time":"2022-07-11T21:57:53Z","timestamp":1657576673000},"page":"960","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Effect of Superheat Steam on Ejector in Distilled Water Preparation System for Medical Injection"],"prefix":"10.3390","volume":"24","author":[{"given":"Bin","family":"Yang","sequence":"first","affiliation":[{"name":"Institute of Marine Science and Technology, Shandong University, Qingdao 266237, China"}]},{"given":"Xiaojing","family":"Ma","sequence":"additional","affiliation":[{"name":"Institute of Marine Science and Technology, Shandong University, Qingdao 266237, China"}]},{"given":"Hailun","family":"Zhang","sequence":"additional","affiliation":[{"name":"Institute of Marine Science and Technology, Shandong University, Qingdao 266237, China"}]},{"given":"Wenxu","family":"Sun","sequence":"additional","affiliation":[{"name":"Institute of Marine Science and Technology, Shandong University, Qingdao 266237, China"}]},{"given":"Lei","family":"Jia","sequence":"additional","affiliation":[{"name":"School of Control Science and Engineering, Shandong University, Jinan 250061, China"}]},{"given":"Haoyuan","family":"Xue","sequence":"additional","affiliation":[{"name":"School of Control Science and Engineering, Shandong University, Jinan 250061, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"138","DOI":"10.1016\/j.apenergy.2019.01.185","article-title":"A comprehensive review of ejector design, performance, and applications","volume":"240","author":"Tashtoush","year":"2019","journal-title":"Appl.
