Our goal with this thesis was to document the performance of three cyclone separators with- and without outlet element, by measuring pressure drop and separation efficiency. Power and Gas Experience Level: Finspang, Sweden Job Family: About the project This project was a collobration between the task master Alfsen and Gunderson AS and our group, consisting of four mechanical engineer students at Oslo and Akershus University College of Applied Science. Forced response simulations are however very costly, especially when full degree models are used.
It is desired to have the highest possible separation efficiency and the lowest possible pressure drop, though these two often go hand in hand. Finally, you can see a short video from the simulation of particle separation. This model accurately predicts the effect of process parameters inlet air flow rate, temperature on the particle dynamics and the particle residence time inside the spray zone. Below, the overall separation efficiency- and pressure drop diagrams, are shown at various volume flow rates.

There are several ways to design the outlet element. PDF format is widely accepted and good for printing. All Text Images Audio Video. The CFD calculations should include time marching full annulus simulation and single passage HB simulation. You’ll joinof the smartest minds all working together to build a better future. The bachelor thesis was conducted and written by four students at HiOA over the course of the spring staf.
Numerical investigation of cyclone separators with- and without outlet element
These challenges require innovative solutions and products that combine both physical and digital technology, which cover the entire energy value chain. Our goal with this thesis was to document the performance of three cyclone separators with- and without outlet element, by measuring pressure drop and separation efficiency.
Please thrsis that the role might be added before last application date. Parallelly with the literature study we had stsr master a computational fluid dynamics CFD software. Cite Export Share Print Email.
The main focus in the thesis was to study this effect. Section plane, which shows the tangential velocity in the cyclone.

This was found after simulating the airflow and comparing the results, which had to be relatively similar. Although cyclones are geometrically simple, the physics describing the flow is rather complicated.
For questions about the recruitment process contact Malin Tallberg, tel. Section plane, which shows the static pressure in the cyclone.
Our main working tasks are development of existing and future engines. Either Can’t find what you are looking for? Separation efficiency Pressure drop. The framework relies on coupled CFD—DEM simulations to provide particle-level mechanistic information such as collision frequencies, particle flux and residence time of the particles in the spray zone. Afterwards, the separation efficiency was calculated.
Simulated streamlines for airflow in the cyclone. This generated various results, which we analyzed and discussed. Cyclone separators are widely used in several industries for separation of particles or droplets from gases or liquids.
We also give support to other departments such as manufacturing, sales, commissioning and service.
