Experimental validation of a time-domain approach for determining sectional loads in a floating wind turbine hull subjected to moderate waves
(Journal article; Peer reviewed, 2017)To achieve cost-effective and reliable structural design of floating wind turbines, efficient and accurate time domain numerical approaches are required to analyse structural responses in design conditions, e.g. wind and ... -
Experimental validation of analytical wake and downstream turbine performance modelling
(Journal article; Peer reviewed, 2018)Wake effects in wind farms can cause significant power losses. In order to reduce these losses layout and control optimization can be applied. For this purpose, simple and fast prediction tools for the wake flow are needed. ... -
Experimental Validation of Angular Velocity Measurements for Wind Turbines Drivetrain Condition Monitoring
(Chapter, 2019)Drivetrain bearings are seen as the most common reason of the wind turbine drivetrain system failures and the consequent downtimes. In this study, the angular velocity error function is used for the condition monitoring ... -
Experimental validation of attitude and rate-sensor bias filter using range-difference measurements
(Peer reviewed; Journal article, 2018)This paper considers the problem of constructing a filter for estimating attitude and rate-sensor bias, that has both proven stability and close-to-optimal performance with respect to noise. The filter is based on measuring ... -
Experimental Validation of End-Effector Stabilization for Underwater Vehicle-Manipulator Systems in Subsea Operations
(Journal article, 2018)This paper considers the kinematic control approach for controlling an underwater vehicle-manipulator system. Three different kinematic control schemes have been applied, and the performance of each scheme is compared. The ... -
Experimental validation of pressure drop models during flow boiling of R134a – effect of flow acceleration and entrainment
(Journal article; Peer reviewed, 2018)A crucial step to assure proficient work of power and process apparatus is their proper design. A wide array of those devices operates within boiling or condensation of the working fluid to benefit from high heat transfer ... -
Experimental Verification of CO2 Dissolution Rate Due to Diffusion Induced Convection
(Journal article; Peer reviewed, 2017)An experimental setup has been designed for measuring the dissolution rate of buoyant CO2 into the water phase below. Experiments were performed in a high-pressure cell, where the water phase was stabilized by a porous ... -
