Dependence of wind turbine loads on inlet flow field
Hanssen-Bauer, Øyvind Waage; De Vaal, Jacobus Bernardus; Tutkun, Murat; Asmuth, H.; Ivanell, S.; Stenbro, Roy (Peer reviewed; Journal article, 2020)In wind farm simulations, the inflow wind field plays a crucial role in the accuracy of both power production, structural load predictions and the turbulent wake development behind wind turbines. Three different inflow ... -
Experimental investigation of transitional oil-water pipe flow
Schümann, Heiner (Doctoral thesis at NTNU;2016:164, Doctoral thesis, 2016)In this thesis transitional oil-water pipe flow is experimentally studied. Here the word transitional relates to two main topics. First, the study focuses on the investigation of transitional flow patterns and resultant ... -
Experimental study of dispersed oil-water flow in a horizontal pipe with enhanced inlet mixing, Part 1: Flow patterns, phase distributions and pressure gradients
Schümann, Heiner; Tutkun, Murat; Yang, Zhi Lin; Nydal, Ole Jørgen (Journal article; Peer reviewed, 2016)The study demonstrates how a disturbance of the flow can affect the pressure gradient and further needs a considerable development length to recover. This is of importance for experimental studies as well as industrial ... -
Experimental study of dispersed oil-water flow in a horizontal pipe with enhanced inlet mixing, Part 2: In-situ droplet measurements
Schümann, Heiner; Tutkun, Murat; Nydal, Ole Jørgen (Journal article; Peer reviewed, 2016)Droplet size measurements in premixed oil-water flow are presented. Three traversable focused beam reflectance measurement probes (FBRM) positioned along the test section allowed for measuring averaged droplet size profiles ...
