1. 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
2. Development and Application of Pure Rotational CARS for Reactive Flows
Sammanfattning : The thesis deals with the further development of pure rotational coherent anti-Stokes Raman spectroscopy (RCARS) for improving the capabilities of gas phase thermometry. The main effort has been to make the technique more robust when employed under a wide range of temperatures and operational conditions. LÄS MER
3. Flow instabilities in centrifugal compressors at low mass flow rate
Sammanfattning : A centrifugal compressor is a mechanical machine with purpose to convert kineticenergy from a rotating impeller wheel into the fluid medium by compressingit. One application involves supplying boost air pressure to downsized internalcombustion engines (ICE). LÄS MER
4. The influence of inertia on the rotational dynamics of spheroidal particles suspended in shear flow
Sammanfattning : Dispersed particle flows occur in many industrial, biological and geophysical applications. The knowledge of how these flow behave can for example lead to improved material processes, better predictions of vascular diseases or more accurate climate models. LÄS MER
5. Angular dynamics of non-spherical particles in linear flows related to production of biobased materials
Sammanfattning : Dispersed particle flows are encountered in many biological, geophysical but also in industrial situations, e.g. during processing of materials. In these flows, the particles usually are non-spherical and their angular dynamics play a crucial role for the final material properties. LÄS MER
