1. Geometry dependency of cerebral arterial pressure, and estimation of wall shear stress in patients with carotid stenosis: a CFD approach
Master-uppsats, Umeå universitet/Institutionen för fysikSammanfattning : This thesis have investigated how the cerebral arterial pressure can be estimated using computational fluid dynamics (CFD). Specifically, a sensitivity study of how the blood vessel diameter affects the arterial pressure in patients with carotid stenosis, has been conducted. LÄS MER
2. Study of tip clearance flows
Master-uppsats, KTH/FlygdynamikSammanfattning : The tip leakage vortex is responsible for the generation of stagnation pressure losses inside the compressor along with the outbreak of rotating stall and surge. The current paper analytically proved that a part of the losses is proportional to the vortex circulation squared. LÄS MER
3. CFD on Open Wet Cutch to Reduce Drag Losses
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : As the need for highly efficient transmission systems increase, it is imperative to have lower fuel consumption levels. Hence, it becomes crucial to investigate and understand reasons behind various losses occurring within the system. Clutches and gears contribute to the major losses within a transmission system.

4. CFD modelling of Retention Aids Dosage Nozzles
Master-uppsats, KTH/MekanikSammanfattning : The objective of this project is to design, using computational fluid dynamics (CFD), a set of retention aid dosage nozzles that minimize shear levels during their operation. This includes the effect of dosage nozzle size, contour and dosage velocity - absolute and relative to the stock flow. LÄS MER
