1. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. READ MORE

2. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Additive manufacturing (AM) has largely improved design freedom compared with traditional manufacturing processes such as casting and milling. The layer-by-layer workflow makes it possible to produce objects with much more complex shapes and structures. READ MORE

3. THE WIND OF CHANGE – SENSITIVITY OF THREE PARAMETERS ON WIND POWER ENERGY CALCULATIONS USING WINDPRO SOFTWARE
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Many parameters used for Wind Resource Assessment (WRA) have uncertainty and variability, yet are input into the process as single values. The extent of the uncertainty or variance may not be known, and may or may not be significant enough to affect output. READ MORE

4. The Influence of Roughness on Electrical Properties of Single Rock Fractures
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : To investigate the relationship between the structural characteristics of rough single fracturesand the electrical properties of the rock. In this study, a series of physical models of roughand smooth single fractures were established using the finite element method and Ohm's lawto test the electrical conductivity. READ MORE

5. Study of a vertical slot fish ladder : Evaluation of flow dynamics through a standardized bypass and the effect of predesigned roughness elements
University essay from Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskapAbstract : Migrating freshwater fish population has been significantly declined, mostly by the obstruction of their migratory routes by hydropower dams. To diminish such impacts, fish ladders have been developed to facilitate the passage of migrating fish. READ MORE
