1. Unsteadiness of blood flow in 90-degree bifurcations
Sammanfattning : .... LÄS MER
2. Dizziness and Benign Paroxysmal Positional Vertigo among older adults - health-related quality of life and associated factors
Sammanfattning : Dizziness is a common complaint reported by more than 30% of persons over 70 years of age and accounts for 2% of all visits in healthcare annually. Benign paroxysmal positional vertigo (BPPV) is a common and treatable cause of dizziness. LÄS MER
3. Studies of Transient and Pulsating flows with application to Hydropower
Sammanfattning : The rotational motion of a hydraulic turbine runner makes pulsating flows ubiquitous in different locations of the machine. The cyclic loading thus induced may generate large pressure forces acting periodically on both stationary and rotating parts. LÄS MER
4. Blood Flow variations in Large Arteries due to non-Newtonian rheology
Sammanfattning : The blood is a complex fluid that contains, in addition to water, cells, macro-molecules and a large number of smaller molecules. The physical properties of the blood are therefore the result of non-linear interactions of its constituents, which are influenced by the local flow field conditions. LÄS MER
5. Effects of boundary conditions and unsteadiness on draft tube flow
Sammanfattning : The present research focuses on flow properties of the elbow draft tube. This element has a major function in low head turbines, since up to half of the losses may arise there at part load. The use of computational fluid dynamic (CFD) to redisign a draft tube necessitates detailed knowledged of the boundary conditions. LÄS MER
