Effect of Variations Throat Length on Ejector Performance

Makmur Saini, Sattar Yunus, Rusdi Nur, Ibrahim Ibrahim


In the present work, experimental investigations have been carried out on ejectors with throat length variation, the changes in throat length variation in the ejector was affect the vacuum pressure produced, of the three variations of throat length tested it , where the length of each throat is 10 cm, 20 cm and 30 cm with throat diameter that same is 2 cm and the diameter of the vacuum cylinder ie 30 cm. The results is the highest vacuum pressure value is in the experiment using a throat length of 30 cm with a vacuum pressure of 87.5 kPa. while the lowest vacuum pressure using a throat length of 10 cm with a vacuum pressure of 90.5 kPa.
