Measuring air bubble layer characteristics around the hull of a ship model
24 okt. 2023
The effect of an air bubble layer around the hull of a ship, a so-called ‘Masker’ system, was evaluated with a new measurement system. The goal of ...
Paper
Evaluating Experimental and Analysis Uncertainty in Resistance Testing
24 okt. 2023
At the AMT’19, an uncertainty model for the evaluation of the combined uncertainty in hydrodynamic model testing was presented [1]. This ...
Paper
In situ measurements of void fractions and bubble size distributions in bubble curtains
24 jan. 2023

Sheet Cavitation Inception Mechanisms on a NACA 0015 Hydrofoil
18 okt. 2020
Experimentally measured trajectories of a series of free-stream nuclei and their growth while passing an isolated roughness element on a hydrofoil ...
Paper
A Lagrangian analysis of scale effects on sheet cavitation inception
26 mei 2019
Sheet cavitation on foils and propellers is often initiated by free-stream bubbles. Consequently, scale effects on cavitation inception occur due to ...
Paper
Random uncertainty of statistical moments in testing - Mean
22 apr. 2019
Stationary tests to find mean values are common in testing; e.g. when measuring the resistance force of a model ship in a towing tank facility. ...
Paper
Exploratory measurements of cavitation nuclei in the wake of a ship model
18 okt. 2017
Cavitation is an important phenomenon influencing the performance of ship propellers and rudders. It is well known that if substantial cavitation ...
Paper
A review of sheet cavitation inception mechanisms
10 apr. 2016
A review is made of the physical mechanisms of sheet cavitation inception. Next to the local pressure, also the characteristics of fluid, solid ...
Paper
Bubble-induced sheet cavitation inception on an isolated roughness element
6 dec. 2015
The nucleation process on an isolated roughness element, located at the point of minimum pressure of a NACA 0015 hydrofoil was studied ...
Paper
Uncertainty Analysis and Stationarity Test of Finite Length Time Series Signals
1 okt. 2015
In Experimental Fluid Dynamics (EFD), the finite length of e.g. a towing tank induces start-up effects, end effects and random uncertainty in the ...
Paper
Uncertainty analysis of finite length measurement signals
17 sep. 2013
The finite length of a towing tank induces a random uncertainty in the mean value of a measurement signal. This uncertainty is not negligible if the ...
