  abstract     = {{This master thesis was performed in collaboration with NP Innovation. The purpose of this project was to develop a new inlet channel and two adapters for a water filter used in fish farming. Two different sizes of filters are included in the company's product portfolio. For both filters there is one inlet channel each in a corresponding size. One inlet channel consist of an adapter welded to the filter and a channel mounted on the adapter. It was established that it would be beneficial for the company if one universal channel was used instead, with the adapters made to fit different sizes of the filter. This would result in decreased production costs for the company. 

The project was structured according to Ulrich & Eppinger Design Methodology. It contained planning, benchmarking, concept development and Design for Manufacturing. The project stops before production ramp-up. The concept development phase included generating ideas in CAD, and then testing them with CFD analysis. The CFD analysis was made to compare the concepts with each other, with the current inlet channel, and against the product specifications. The final concept was chosen through the concept selection phase that included concept screening, concept combination and concept scoring.

Initial simulations were made on the company's current solutions to set a benchmark for the final concept. One of the company's solutions showed severe recirculation and dead zones while another already gave an acceptable flow. During the concept development phase, it was discovered that the edge of the inlet channel causes the main separation of the flow in the inlet channel. 

The deliverable to the company is a CAD model of a final concept. The final concept includes a rounded wall guiding the water into the inlet channel. The solution decreases recirculation and distributes the flow throughout the entire channel, while maintaining an acceptable velocity for the water. The manufacturing has slightly worsened in the complexity of the channel, but improvements were made in relation to only having one channel instead of two. 

While solving the problem in this master thesis, it also brings further development and opportunities for the health and safety of fishes in fish-farms.}},
