1. 1. Design of an Embedded Torque Sensor : Based on Volumetric Strain induced Differential Air Pressure

   University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

   Author : Wen Qi; [2022]
   Keywords : Torque; Electronics; Gas sealing; Pressure measurement;

   Abstract : This paper proposes a torque sensor based on the differential air pres- sure measurement method using a new embedded structure. The pro- posed sensor design is an improvement over the previous sensor design. The mechanical sensitivity, resolution, and stress distribution of the new sensor are analyzed by finite element modeling. READ MORE

3. 2. Measurement of Thermal Insulation properties of TBC inside the Combustion chamber

   Author : Siamak Kianzad; [2017]
   Keywords : Materials; TBC; Thermal barrier coating; heat flux; crack; combustion chamber; heavy duty diesel engine; single-cylinder; dummy valve; 8YSZ; YSZ; segmented cracks; radiative heat transfer; lanthanum gadolinium; EB-PVD; PVD; APS; CVD; horizontal cracks; vertical cracks; crack propagation; crack initiation;

   Abstract : This master thesis project was performed in collaboration with Scania CV AB, Engine Materials group. The purpose with the project was to investigate different ceramic TBC (Thermal Barrier Coating) thermal insulation properties inside the combustion chamber. READ MORE

4. 3. Gårdsbaserad uppgradering av biogas med askfilter

   University essay from SLU/Dept. of Energy and Technology

   Author : Ulf Hävermark; [2017]
   Keywords : småskalig; fordonsgas; demonstrationsförsök; fixering; koldioxid; svavelväte;

   Abstract : Most of the biogas produced in small scale biogas plants in Sweden today is used for combined heat and power production. With the price of electricity being relatively low, the small biogas plants are hardly profitable. READ MORE

5. 4. Design of a rotary valve for pressurised steam

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Talent Nyawo; [2016]
   Keywords : rotary valve; uniflow engine; gas-tight sealing; variable cut-off time; high-pressure-high-temperature; roterande ventil; uniflow motor; gastät försegling; rörlig bryttidpunkt; hög-tryck-hög-temperatur;

   Abstract : Denna rapport är gjord på ett examensarbete som var utfört på uppdrag av det svenska företaget Ranotor AB. Syftet var att utveckla en konceptuell lösning för en rotationsventil som skall fungera i en miljö med hög temperatur och högt tryck. Ventilen skall arbeta under höga rotationshastigheter, vilket kräver korta öppettider. READ MORE

6. 5. Isothermal Oxidation Study of Gd2Zr2O7/YSZ Multi-Layered Thermal Barrier Coatings

   University essay from Högskolan Väst/Avd för tillverkningsprocesser

   Author : Ran Li; [2015]
   Keywords : Multi-layered thermal barrier coating; isothermal oxidation; suspension plasma spray;

   Abstract : Conventional yttria stabilized zirconia (YSZ) are widely used in the gas turbine to protect the substrate material from high temperature. But the common YSZ top coatings have limitations at higher temperature (above 1200 ℃) due to significant phase transformation and intensified sintering effect. READ MORE
