21. Construction and Validation of a Lab-scaleBorehole Thermal Energy Storage Model
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Borehole heat exchangers are widely used in heat pumps of residential buildings and industrialsystems. It is known as one of the most energy ecient technologies which provides heatingand cooling by using sustainable geothermal energy. The life time of borehole heat exchangerslasts more than 50 years which is longer than combustion boilers. LÄS MER
22. Sammankoppling av tryckluftssystem i SBC
M1-uppsats, KTH/Hållbar produktionsutveckling (ML)Sammanfattning : Detta examensarbete har genomförts på AstraZenecas produktionsanläggning i Gärtuna, Södertälje och behandlar ett av AstraZenecas dyraste media, tryckluft. Mer specifikt behandlar rapporten tryckluftsanläggningen i byggnad 921 (B921) där optimal drift på kompressorerna inte har lyckats uppnås på grund av att kapaciteten på kompressorerna inte matchar flödesbehovet i byggnaden, som i sin tur har skapat onödiga kostnader och utgifter.

23. CFD investigation of Plate Channels
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : Alfa Laval has a wide product range for plate heat exchangers that can be applied in most industries. The constant development of new and old heat exchangers drive the need for new and efficient methods that can reliably be used in the development process. LÄS MER
24. Investigation of robustness of a SiC MOMS pressure sensor in high pressure/temperature operation conditions
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Rigorous environmental policies and the need for higher fuel economy continuously demand new innovations in the combustion process of automotive engines. Consequently, there is an increasing necessity for active monitoring of the combustion event, and therefore, microsystems have started coming into play. LÄS MER
25. Experimental pressure loss analysis in a mini tube for a fully developed turbulent airflow. : Mini channels of lengths 22.5 mm to 150 mm in length with a constant diameter of 1.5 mm
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : The cooling systems in a gas turbine are especially important as the turbine blades and vanes are exposed to extreme temperatures. The relatively cool air is extracted from the compressors and fed to the turbines to cool the turbine blades. LÄS MER
