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.

Die Pläne können ganz einfach von Grund auf neu generiert werden oder auf Grundlage von DXF-, DWG- oder PDF-Dateien eingelesen werden.

APF WoodPanel lets you design timber slabs (XLAM or CLT), according to Eurocode 5 (EC5). All you have to do is specify the dimensions, the configuration and the actions. APF WoodPanel performs all the required checks for ULS, according to Eurocode 5. The results are displayed in the graphic environment and the user can save a detailed report with calculation details and images. The user interface is designed to simplify your work. You can change every value (cross sections’ size, timber beam length, etc.), recalculate and the results are immediately available. All the design variables, such as load coefficients, material properties (mechanical properties of timber), can be adjusted by you, according to your needs (or the requirements of any National Standard or National annex to the Eurocodes). APF WoodPanel performs a structural analysis of the panel calculating the normal and shear stresses in the crossed layers. The forces and stresses acting on the panel faces are displayed by the graphical interface, for each load case separately.
