Abstract

fetched live from OpenAlex

This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today’s equipment. During the project several concept suggestions were developed using customer interviews and research as input. The concepts were evaluated and a winner was selected and was developed further. This final concept was analysed considering primarily performance, production cost, solid mechanics and rotor dynamics. The result was named Skarven. Its cleaning technology is made out of a spinning disc stack that with centrifugal force separates the oil from the airflow. The disc stack is enclosed by a cylindrical shell and is powered by an electric motor. The small size and weight makes it possible to mount Skarven directly on the machine, which is preferable. The low manufacturing cost and the simple design makes it cheaper, lighter, smaller and easier to maintain than the competitive products. The conclusion of this thesis is that Alfa Laval’s gas separator can be readapted to greater gas flows and have a good chance to gain market shares in the oil mist eliminator business with this design.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
