1. 21. 3D Printed Lattice Structure for Driveline Applications

   University essay from KTH/Materialvetenskap

   Author : Boyu Xue; [2021]
   Keywords : Lattice structure; AM Additive Manufacturing ; topology optimization; lattice optimization; NVH noise; vibration and harshness ; mechanical performance; lightweight; driveline; natural frequency; Gitterstruktur; AM additiv tillverkning ; topologioptimering; optimering av gitter; NVH buller; vibrationer och obehag ; mekanisk prestanda; lättvikt; drivlina; egenfrekvens;

   Abstract : Lattice structures have received a lot of attention as cellular materials in recent years because of their outstanding properties, such as high strength-to-weight ratio, heat transfer, energy absorption, and capability of improving noise, vibration and harshness (NVH) behavior. This type of structure received a boost from additive manufacturing (AM) technology, which can fabricate geometries in practically any shape. READ MORE

3. 22. Bubble Dynamics on Artificial Nucleation Sites in Boiling Heat Transfer

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

   Author : Yuqing Zhang; [2021]
   Keywords : ;

   Abstract : Pool boiling heat transfer is a complicated scientific problem due to the complex phase change process. In recent years, with the development of nuclear technology, microelectronics and space exploration, more attention has been paid to boiling which present great potentials for the thermal management in these applications because nucleate boiling has much better heat transfer performance than single-phase fluid, while bubbles, including their departure frequency and diameter and the interaction between bubbles plays an important role in determination of the heat transfer performance.

4. 23. Towards a virtual climate chamber – A physical experimental study

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Javier Arroyo Molina; [2020]
   Keywords : climate chamber; airflow; experimental characterization; energy; thermal cooling; klimatkammare; luftflöde; experimentell karakterisering; energi; termisk kilning;

   Abstract : This project focuses on experimentally characterizing one of the tools used at Ericsson AB to test product performance, the climatic chamber. By conducting experiments inside the climate chamber and post processing the data obtained, the airflow inside it can be understood and compared to outdoor experimental data. READ MORE

5. 24. Design and Development of an Experimental Test Rig for Heat Sinks

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Gabriel Kaduvinal Abraham; [2020]
   Keywords : Cooling; Experimental Setup; Flow rate; Heat sink; Plumbing; Sensors; Thermal Efficiency; Kylning; experimentell installation; flödeshastighet; kylfläns; VVS; sensorer; värmeeffektivitet;

   Abstract : Heat sinks are used mainly to take away the excessive heat which are produced in a component. This transfer of heat enables a smooth operation of the system with the heat generating component. The efficiency of heat sink is often dependent on the amount of heat it can take away within the smallest duration of time. READ MORE

6. 25. Fluid field analysis on a flexible combustor for a hybrid Solar / Brayton system : A numerical study

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

   Author : PAUL JACQUEMARD; [2020]
   Keywords : CFD; MGT; LPP Combustor; Impinging hole; CFD; MGT; LPP-brännare; slaghålsvägg;

   Abstract : Recent improvements to concentrating solar dish systems lead to further focus on hybridization systems for small-scale power generation applications. Variability of the solar load creates new requirements for combustion systems. READ MORE
