1. 1. Turbulence Intensity Measurements in a High-Pressure Gas Turbine Stage

   University essay from KTH/Kraft- och värmeteknologi

   Author : Ettore Scami; [2022]
   Keywords : Turbulence Intensity; turbine; stage efficiency; grid; turbomachinery; length scales;

   Abstract : This Thesis work focused on the acquisition and evaluation of data on mean velocity, turbulence intensity and length scales obtained via hot wire measurements in a high pressure single-stage land-based turbine available at the Department of Heat and Power Technology in KTH. Turbulence was generated by the use of grids and twoprobes, upstream and downstream of the turbine stage, were used. READ MORE

3. 2. Analysis of wall-mounted hot-wire probes

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Alvisi Alex; Perez Adalberto; [2020]
   Keywords : Turbulent Boundary layer; Turbulent Channel Flow; Hot Wire Anemometer; Direct Numerical Simulations; Immersed Boundary Method;

   Abstract : Flush-mounted cavity hot-wire probes have been around since two decades, but have typically not been applied as often compared to the traditional wall hot-wires mounted several wire diameters above the surface. While the latter suffer from heat conduction from the hot wire to the substrate in particular when used in air flows, the former is belived to significantly enhance the frequency response of the sensor.

4. 3. Compact safety system for automatic flagpole : Flow sensor anemometer

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : David Ström; Carl Jensen; [2019]
   Keywords : Mechatronics; Thermal Mass Flow Sensor; Anemometer; Automatic Flagpole; Automation; Mekatronik; Flödessensor; Anemometer; Automatisk Flaggstång; Automation;

   Abstract : Automating tasks and processes are becoming more and more common in both corporate and everyday life. The aim of this project is to assist the company Hotswap in the development of a safety system for an existing automatic flagpole. READ MORE

5. 4. Revisiting Hot-Wire AnemometryClose to Solid Walls

   University essay from KTH/Mekanik

   Author : Yuta Ikeya; [2017]
   Keywords : ;

   Abstract : A well-known problem of hot-wire anemometry (HWA), is the “wall effect”, namely theoverestimation of the measured velocity near a wall. The overestimation occurs due toadditional heat loss from the heated wire-sensor to the wall. READ MORE

6. 5. LES Simulation of Hot-wire Anemometers

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Assiye Süer; [2017]
   Keywords : Hot-wire anemometer; Hot-film anemometer; Computational Fluid Dynamics; Mars Science Laboratory; MSL; Mars; Large Eddy Simulations; LES; Reynolds-Averaged Navier–Stokes equations; RANS;

   Abstract : Hot wire anemometers have been used in several wind velocity sensors deployed in Mars. They are based in keeping the temperature of a surface at a constant value, above the ambient. This is done by means of a heater controlled with an electronic system. READ MORE
