16. Managing in turbulence : an empirical study of small firms operating in a turbulent environment
Sammanfattning : This thesis deals with how small firms, and especially their CEOs, manage their situation in times of high environmental turbulence. Eight firms have been chosen for the empirical study based on their performance and the CEO’s self-efficacy and tolerance for ambiguity. LÄS MER
17. Numerical approaches to droplet growth in atmospheric turbulence
Sammanfattning : The bottleneck problem of cloud droplet growth is one of the most challenging problems in cloud physics. Cloud droplet growth is neither dominated by con-densation nor gravitational collision in the size range of 15–40 μm in radius. Turbulence-generated collision has been thought to be the mechanism to bridge the size gap, i.e. LÄS MER
18. Hydrodynamic stability and turbulence in fibre suspension flows
Sammanfattning : .... LÄS MER
19. The Influence of Atmospheric Turbulence on Barrier Sound Reduction
Sammanfattning : Numerical modelling and measurements are used for studying the reduced performance of a noise barrier, caused by a turbulent atmosphere. The turbulence scatters the sound, which leads to an increased noise level in the acoustic shadow region behind the barrier. LÄS MER
20. Turbulence modeling of compressible flows with large density variation
Sammanfattning : In this study we highlight the influence of mean dilatation and mean density gradient on the Reynolds stress modeling of compressible, heat-releasing and supercritical turbulent flows.Firstly, the modeling of the rapid pressure-strain correlation has been extended to self-consistently account for the influence of mean dilatation.
