… is put on finding a joint that works well without lubrication or with water in the contact. The wobble plate is studied by finding a kvasi-static operation point from a dynamic load modell of the steam expander and applying these in static FE-modelled simulations. The wobble …
Kartläggning av nuvarande fjärrkylasystem och framtida utvecklingsmöjligheter
… in the system interact to achieve an optimized use of the distributed cold water. In addition this report also addresses the parameters that affect a building's cooling load and the measures that can reduce the power load, which is the main parameter that limits the number of …
En fallstudie för att främja den småskaliga, såsom storskaliga vattenkraften
… 50 % lower mortality rate than a Francis turbine with a corresponding drop and water intake and at full load. At part load the mortality rate is 42 % less. Case 1 and 2 indicates that a Kaplan turbine is more fish friendly than a Francis turbine, but Case 3, indicates the …
Design and finite element analysis
… operated vehicle) to release the cap from the hubface when it is placed under water. The cap KC3-12 was found to fulfil the criteria under the test load pressure, according to ASME VIII, div2. The analysis shows that a higher pressure can be allowed on the cap since the collapse …
… and implemented in the turbine model. The model describes how the flow of water and the turbine torque are affected by the deviations from the optimal combination curve of the wicket gate and runner blade angles, based on a hydropower unit with available test data. Also the …
… mixture had to be well known, in this case a mixture of ammonia and water. The thermodynamics of the different components is also studied and discussed in the report. The VARS consists of four heat exchangers that rejects/absorbs heat to/from external sources; the evaporator …
bestämning av flödesvägar och åtgärdsförslag för optimal fosforbindning vid avloppsrening med reaktiva filter
Discharge of untreated wastewater leads to unnaturally high levels of nitrogen and phosphorus in rivers, lakes and the sea, which results in unbalanced ecosystems with eutrophication and lack of oxygen. Part of the phosphorus in surface waters is coming from on-site wastewater …
fördröjd groning hos raps : försök med frö-coating samt litteraturgenomgång om frögroning, coating och praktisk tillämpning i reläodling
… an acid, base or a neutral phase. The function of the wax was to prevent water, which is a primary factor for germination, to reach the seed. The base or acid phase was hypothesised to break down the wax slowly and subsequently enable the seed to take up water and germinate. The …
… of the possibility to collect the pollutants to reduce the load to the water and improve the water quality. The quantity of pollution transport from the most trafficated roads areas in Örebro city has been calculated. Roads whith a traffic exceeding 10 000 vehicle/day. The study …
