Ejectors have found wide application in various industries due to their simplicity, unpretentiousness to operating conditions, absence of tribological problems, etc. Their main drawback is related to the low efficiency, which is at the level of about 30%. The need to improve operational characteristics led to the creation of an innovative ejector with a combined mixing chamber (initial conical and subsequent cylindrical parts). A mathematical model based on balance equations is proposed for the possibility of determining the ejection coefficient (the main flow rate characteristic) when designing or auditing equipment
