Mathematical model of the process of gas pumping by a multi-nozzle supersonic vacuum ejector

Currently, vacuum ejectors are used in various industries due to a number of advantages. However, classic single-nozzle ejector configurations have a number of disadvantages that limit their application in various installations. A mathematical model of the gas pumping process by a multi-nozzle supersonic vacuum ejector has been developed. The calculation scheme, accepted assumptions and main calculation dependencies used in the mathematical model of the working process of a multi-nozzle supersonic ejector are presented, and also a program for calculating the pumping speed of a multi-nozzle supersonic vacuum ejector and block diagram of this program have developed. Conclusions have been made.
