STAR CCM+ THESIS

Turn challenges into opportunities Our energy system is undergoing rapid changes and the world’s energy use is steadily increasing. The bachelor thesis was conducted and written by four students at HiOA over the course of the spring semester: Simulated streamlines for airflow in the cyclone. The pressure drop relates to the power needed to operate the cyclone. In addition to this, two vortex finder diameters were simulated and compared. Parallelly with the literature study we had to master a computational fluid dynamics CFD software. Simulated particles in the cyclone separator with “Lagrangian multiphase”-model.

Parallelly with the literature study we had to master a computational fluid dynamics CFD software. Process summary The work started with modeling the geometry of the cyclones and create a fine independent mesh. Rutgers University Community Repository.

Development of two-way coupled CFD – DEM model for top spray fluid bed granulator using star CCM+

The pressure drop relates to the power needed to operate the cyclone. There is limited documentation of the effect created by an outlet element on the flow in the cyclone. Process summary The work started with modeling the geometry of the cyclones and create a fine independent mesh.

Whole Engine department We are 14 persons who are responsible for rotor and blade dynamics as well as secondary air systems in our gas turbines Power output: Generated mesh for the cyclone divided the cyclone in small cells.

Numerical investigation of cyclone separators with- and without outlet element

For questions about the recruitment process contact Malin Tallberg, tel. This documentation would help Alfsen and Gunderson to expand their portfolio. The outlet element is an optional part that can be connected to a cyclone.

Through numberious simulations, the overall performance of the separtion with outlet element were obtained and reported. 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.

Forced response simulations are however very costly, especially when full degree models are used.

Created 3D-model of the cyclone. Parallelly with the literature study we had to master a computational fluid dynamics CFD software. 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 tgesis spray zone.

For questions about the role please contact the main supervisors: Over decades, thesiss researchers have studied these devices and have developed number of theories and empirical models for design purpose. Simulated particles in the cyclone separator with “Lagrangian multiphase”-model.

This model accurately predicts the stsr of process parameters inlet air flow rate, temperature on the particle dynamics and the particle residence time inside the spray zone. We also give support to other departments such as manufacturing, sales, commissioning and service. We then continued to with injecting particles to the cyclone.

GROUP 11 – BACHELOR THESIS

Rights The author owns the copyright to this work. Cyclone separators are widely used in several industries for separation of particles or droplets from gases or liquids. Graph of axial velocity for 6A. There are several ways to design the outlet element. The bachelor thesis was conducted and written stat four students at HiOA over the course of the spring semester:. Note by Dheeraj Reddy Devarampally.

In addition to this, two vortex finder diameters were simulated and compared. Passive scalar model is also used for Lagrangian phase to track the residence time of the particles within the spray zone. Click cc+m for information about Citation Management Tools at Rutgers.
