With Bautagebuch (Site journal) 2019, you get a programme that allows you to complete, edit, print and manage forms in the construction area. During the development of the programme, we paid special attention to ensure that using the software is easy, efficient and quick to learn. Special skills are not required; basic knowledge on how to use Windows is beneficial. This documentation should provide a certain basic knowledge and help you to start working with the site journal. It contains instructions for installing the programme and explains function and effectiveness of operating elements as well as selected processes.

Use EzeJector software as your ONE STOP SERVICE for ejector design. Get quick and accurate results to close in on your best alternative! Or do you need an ejector design done for you? We can size and specify ejectors for a wide range of applications. Or do a rating for an existing ejector. Go to our Case Design Page.​ Your challenge as a process engineer is working out whether an application will work and what the flow rates and conditions are to make it work.

How the ejector energy balance works:

The motive gas accelerates to sonic velocity in the nozzle throat (choked flow) with pressure decreasing by approximately 45% (depending of gas properties). The gas continues to accelerate to Mach >1 in the outlet section of the nozzle, with the pressure reducing to that required to draw in the entrained gas. The ejector nozzle is also known as a De Laval nozzle. Pressure reduction of the motive gas has thus been converted isentropically into usable kinetic energy. Some energy is lost because of isentropic efficiency <100%. The entrained gas is drawn into the mixing section and also accelerates to sonic velocity (there are cases where it does not reach sonic velocity but these are not described here). Once again there is some energy loss due to isentropic efficiency <100%. The motive gas and entrained gas have different velocities. Momentum is preserved as they mix, but kinetic energy is lost. In general, the greater the ratio of motive gas pressure to entrained gas pressure, the greater the loss of kinetic energy. The mixed gas is still supersonic as it leaves the mixing section. A shock wave then occurs as it enters the diffuser . Flow becomes subsonic and a step change increase in pressure occurs. The gas decelerates in the diffuser with kinetic energy being recovered as increased pressure. As above, some energy is lost due to isentropic efficiency <100%. Friction against the internal metal surfaces of the ejector causes additional energy losses.
