1. 1. CFD Study of An Office Room Equipped with Corner Impinging Jet Ventilation

   Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

   Författare :Getiye Wodaje; [2022]
   Nyckelord :CFD in ventilaion; Thermal comfort; Impinging jet ventilation; thermally stratified flow; Corner impinging jet; Office air quality; Indoor environment; turbulent jet;

   Sammanfattning : A CFD validation study was made using corner supplied impinging jet ventilation operating in cooling mode. The air distribution system has two equilateral triangle shaped inlets placed 80cm above the floor at the two that share a common wall. The supply air was introduced at 2.26m/s. LÄS MER

3. 2. Rocket Jet Impinging on a Surface

   Master-uppsats, KTH/Teknisk mekanik

   Författare :Javier Capel Jorquera; [2022]
   Nyckelord :Rocket jet impinging on a surface; Favre-Averaged Equations; turbulence modeling; numerical considerations; Method of Characteristics; MOC; plate optimization;

   Sammanfattning : With the continuous growth of the space industry and the introduction of reusable rockets, the number of rocket launches is expected to increase significantly in the following years. During rocket launching, the engine exhaust impinges on the launch structure producing a complex flow field. LÄS MER

4. 3. CFD study of the different inlet configurations and airflows in a room with IJV

   Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

   Författare :Christos Stiapis; [2022]
   Nyckelord :Ventilation; CFD; Impinging Jet Ventilation;

   Sammanfattning : A method of providing ventilation using impinging jets (IJV) utilizes stratification while delivering air at a high velocity. As a result of this attribute and the simplicity of its terminal construction, IJV offers an advantage over the well-known Displacement Ventilation (DV) system. LÄS MER

5. 4. Turbulence Intensity During Low-Level Jets in the Baltic Sea

   Kandidat-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

   Författare :Thomasson August; [2021]
   Nyckelord :Low-Level Jet; Turbulence intensity; Shear sheltering; LiDAR; Baltic Sea; Low-Level Jet; Turbulensintesitet; Shear sheltering; LiDAR; Östersjön;

   Sammanfattning : Low-level jets (LLJs) are local wind speed maximums in the atmospheric boundary layer. In the Baltic Sea, LLJs are frequently occurring in spring and summer. It is an important phenomena to consider for wind energy parks, and changes in turbulence during the jets can effect the efficiency of said parks. LÄS MER

7. 5. Numerical Investigation of the Near FieldZone Flow Behavior of Isothermal CornerImpinging Jet Ventilation Using CFD

   Master-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

   Författare :Too-chukwu C. Ogbuagu; [2021]
   Nyckelord :Ventilation; Computational fluid dynamics;

   Sammanfattning : 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. LÄS MER
