1. CFD Based External Heat Transfer Coefficient Predictions on a Transonic Film-Cooled Gas Turbine Guide Vane : A Computational Fluid Dynamics Study on the Von Karman Institute LS94 Test Case
University essay from Linköpings universitet/Mekanisk värmeteori och strömningsläraAbstract : The turbine inlet guide vanes of a gas-turbine are subjected to extreme hot gas temperatures which increases the risk of mechanical failure and overall reduces the component lifespan. Hence, it is of great interest for gas-turbine manufacturers to establish methods for accurately estimating the temperature distribution along the vane surface. READ MORE

2. Improving gas flow in gas atomization
University essay from KTH/MaterialvetenskapAbstract : Gas atomization is a cost-effective processing method to produce fine, spheroidized metal powders. During the process, high velocity jets of gas are sprayed at a molten metal stream to break it into small droplets, which will solidify and form the powder particles. READ MORE

3. Numerical Investigation of the Near FieldZone Flow Behavior of Isothermal CornerImpinging Jet Ventilation Using CFD
University essay from Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskapAbstract : Abstract The impinging jet ventilation's importance in providing better air distribution and energy-efficient operation, as well as both its heating and cooling flexibility potential cannot be overemphasized. This is because acceptable indoor air quality and its environmental conditions are essential to occupant’s wellbeing, comfort, productivity, and improved cognitive function. READ MORE

4. External Heat Transfer Coefficient Predictions on a Transonic Turbine Nozzle Guide Vane Using Computational Fluid Dynamics
University essay from Linköpings universitet/Mekanisk värmeteori och strömningsläraAbstract : The high turbine inlet temperature of modern gas turbines poses a challenge to the material used in the turbine blading of the primary stages. Mechanical failure mechanisms are more pronounced at these high temperatures, setting the lifetime of the blade. READ MORE
