Investigation of the Wake Flow behind a stepped circular Cylinder using Particle Image Velocimetry
(Master thesis, 2012)Subject of the present study was the investigation of the wake behind stepped circular cylinders. Experiments were performed using particle image velocimetry (PIV). Cylinder models with diameter ratios D/d=1, D/d=6/5 and ... -
Investigation of thermal transport in polymer composites with percolating networks of silver thin films by the flash diffusivity method
(Journal article; Peer reviewed, 2017)The flash diffusivity method, also known as laser flash analysis (LFA), is commonly used to obtain the thermal diffusivity (α) and thermal conductivity (κ) of materials, due to its relative simplicity, rapid measurements, ... -
Investigation of Thermopressor with Incomplete Evaporation for Gas Turbine Intercooling Systems
(Peer reviewed; Journal article, 2023)One of the promising ways to increase fuel and modern gas turbine energy efficiency is using cyclic air intercooling between the stages of high- and low-pressure compressors. For intercooling, it is possible to use cooling ... -
Investigation of thrust loss due to steering while trawling
(Master thesis, 2017)This thesis investigates the potential for a reduction in required propeller power by optimizing the transverse position of attachment points for trawl warps, simulating a system of movable trawl blocks. Full scale ... -
Investigation of transcritical CO2 vapour compression systems by simulation and laboratory experiments
(Doktoravhandlinger ved NTNU, 1503-8181; 141, Doctoral thesis, 2002)The thesis presents the use of simulation tools and experimental data for investigation of various aspects of the transcritical CO2 vapour compression cycle. This is done through three papers, the first on design and ... -
Investigation of U-tube effect in drilling operation
(Master thesis, 2010)The U-tube effect is present when drilling with a low riser return system(LRRS)or a dual gradient system(DGS). For the LRRS the U-tube effect will initiate asthe surface mud pump is shut down. The mud level in the drill ... -
Investigation of unsteady flow in the vaneless gap between impeller and diffusor.
