Abstract
This is a Master Thesis carried out for and done in cooperation with Getinge Water System A/S. The purpose of the thesis was to develop a new separation system for their Pure Steam Generator. The focus was set on making it smaller without affecting separation efficiency and manufacturing costs. During the projects course, objectives were altered and size was no longer highly prioritized; instead, smaller improvements were to be made on the existing system.
The product development methodology by Ulrich and Eppinger was used during the project. Ideas were generated and evaluated in a series of steps. Criteria were set up and Computational fluid dynamics were used in order to evaluate the ideas.

This is a Master Thesis carried out for and done in cooperation with Getinge Water System A/S. The purpose of the thesis was to develop a new separation system for their Pure Steam Generator. The focus was set on making it smaller without affecting separation efficiency and manufacturing costs. During the projects course, objectives were altered and size was no longer highly prioritized; instead, smaller improvements were to be made on the existing system.
The product development methodology by Ulrich and Eppinger was used during the project. Ideas were generated and evaluated in a series of steps. Criteria were set up and Computational fluid dynamics were used in order to evaluate the ideas.
The most appealing ideas were: adding a baffle in the lower section of the cyclone, changing the number of inlets and reducing their size and changing the inlet design by creating a softer transition to the cylinder part of the cyclone.
Two new separation systems were created from these ideas: one to meet the initial objectives, and one to meet the revised ones. The first solution used a bent outlet pipe, a baffle, and three smaller inlets with the softer design. It was also reduced in size. Numerical results were not fully satisfactory showing an increased pressure drop; however, velocity peaks and the velocity below the outlet, particularly under the baf-fle, were reduced. The second solution used two smaller and softer inlets to increase the efficiency of the product by reducing the pressure drop without making any large or expensive modifications. (Less)
