Either Can’t find what you are looking for? Below, the overall separation efficiency- and pressure drop diagrams, are shown at various volume flow rates. 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.

Please note that the role might be added before last application date. Rutgers University Community Repository. This mechanistic data can be used in Population balance models PBM to model the rate processes such as agglomeration, breakage and consolidation. This thesis started as a literature study were we collected information about cyclone separators and how they work. Process summary The work started with modeling the geometry of the cyclones and create a fine independent mesh. Other Date degree. 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.
The bachelor thesis was conducted and written by four students at HiOA over the course of the spring semester:.
If time frame allows a higher fidelity model considering the hub and shroud cavities could be investigated. Siemens Industrial Turbomachinery AB offer products and solutions for generating sustainable and resource efficient electricity. Forced response simulations are however very costly, especially when full degree models are used.
Either Can’t find what you are looking for? There are several ways to design the outlet element. Note by Dheeraj Reddy Devarampally.
Numerical investigation of cyclone separators with- and without outlet element
Afterwards, the separation efficiency was calculated. 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. Finally, you can see a short video from the simulation of particle separation. The main focus in the thesis was to cccm+ this effect.

This mechanistic data can be used in Population balance models PBM to model the rate processes such as agglomeration, breakage and consolidation.
Simulated particles in the cyclone separator with “Lagrangian multiphase”-model. Simple citation Devarampally, Dheeraj Reddy. Rights The author owns the copyright to this work. The efficiency is measured in total efficiency, which means how much of the particles get separated from the air.
Separation efficiency Pressure drop. Section plane, which shows the static pressure in the cyclone. Section plane, which shows the axial velocity in the cyclone. It is assumed to increase the collection efficiency. There is limited documentation of the effect created by an outlet element on the flow in the cyclone.

We then continued to with injecting particles to the cyclone. Note Includes bibliographical references. Turn challenges into opportunities Our energy system is undergoing rapid changes and the world’s energy use is steadily increasing.
Our main working tasks are development of existing and future engines.
