Description
Steam Ejector Project Description
The steam ejector is a mechanical device that uses a primary (motive) fluid to suck up a secondary fluid (gas, liquid, or solid particles). Eventually, the ejector mix the two primary and secondary fluids and they exit from the outlet. Ejectors have two major tasks, including creating vacuum and gas suction and fluid mixing.
The basis of the ejector is to create a vacuum for the suction of the desired fluid (such as powder, granule, sludge, etc.) based on the continuous conversion of kinetic and pressure energy. The present problem deals with the flow of water vapor as the main fluid (primary) and the secondary fluid (suction) within a convergent-divergent steam ejector.
The present simulation aims to investigate the behavior of primary and secondary fluid after passing through the internal including creating vacuum and gas suction and fluid mixing and the steam ejector diffuser. In the present model, due to the vacuum pressure difference between the two inlet fluids, the suction phenomenon for the secondary fluid has to occur.
The Mach number corresponding to the fluid flow inside the ejector also increases. To analyze this model, we investigate parameters such as Mach number, velocity, and pressure based on the motion of the fluid flow along with the steam ejector.
We design the present 2-D model by the Design Modeler software. We perform the meshing by ANSYS Meshing software. The mesh type is structure. The element number equals 51990.
Methodology
We have used a density-based solver due to the compressibility in this project.
Steam Ejector Conclusion
At the end of the solution process, we obtain contours of pressure, velocity, and Mach number. The present model uses a convergent-divergent nozzle to drive the fluid. The fluid velocity significantly increased so that the fluid velocity exceeds the velocity of sound within the fluid.
The actuator fluid and the secondary fluid then mix and compress.

How does your simulation account for the effects of heat transfer on the performance of the steam ejector?
MR CFD Support –
Our simulation includes heat transfer effects by solving the energy equation along with the fluid flow equations. This allows us to accurately capture the effects of heat transfer on the performance of the steam ejector.

How does your simulation model the complex flow phenomena inside a steam ejector?
MR CFD Support –
Our simulation uses advanced CFD techniques to model the complex flow phenomena inside a steam ejector. This includes modeling the interaction between the primary (high-pressure) and secondary (low-pressure) steam flows, as well as the resulting mixing and condensation processes.

Can your simulation predict the performance of the steam ejector under different operating conditions?
MR CFD Support –
Yes, our simulation can predict the performance of the steam ejector under different operating conditions. You can adjust parameters such as steam pressure and temperature to study their effects on ejector performance.
