1. Testing of AblativeMaterials as a Protective Coating for Rocket Launch Pads
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : As the space market grows, demand for sites to host rocket tests and to launch satellites to orbit is expected to increase. During these activities, the launch infrastructure needs to withstand the extreme thermal and mechanical loads associated with the exhaust of a rocket engine. READ MORE

2. Desert garden techniques to ameliorate urban microclimates : an example of application in Granada, Spain
University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)Abstract : In this day and age we are faced with urban cores getting hotter, with the main drivers being climate change and the urban heat island effect. This gets even more complicated as the parts of Europe that have the largest need too cool down, i.e. the south, has the least amount of space available for interventions in the form of green space.

3. Temperature sensing on a linear wear test rig for plastic components
University essay from KTH/Maskinkonstruktion (Inst.)Abstract : För att verifiera att komponenter håller under en förväntad livslängd kan en Accelererad Livstids Testning (ALT) användas. En av huvudaspekterna som kan förstöra ett ALT-test av plastkomponenter är om kontakttemperaturen överstiger glasövergångstemperaturen. Detta eftersom det förändrar testkomponentens materialegenskaper. READ MORE

4. Heat and fluid control solutions for deep space CubeSat CGPS
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : This thesis is on the subject of how propellant heating considerations affect the design of a CubeSat cold gas propulsion system. Computer simulation tools are used to analyse heat flow through the system, as well as the fluid flow and phase change of butane. READ MORE

5. A Numerical Study of Melt Pool Heat Transfer in the IVR of a PWR
University essay from KTH/FysikAbstract : This thesis aims to provide the thermal condition of melt pool convection by CFD simulation, which is important to the assessment of the invessel melt retention (IVR) strategy widely adopted in Generation III pressurized water reactors (PWRs). As a severe accident mitigation measure, the IVR strategy is realized through external cooling of the lower head of a reactor pressure vessel (RPV). READ MORE
