Abstract:

Single bubbles and drops are recorded with a high speed camera under deep sea conditions in the pressure lab DL2. Velocity curves as function of particle diameter and height above the orifice are developed for methane and oil dependent on pressure and temperature. The dataset contains charts created by observing video of methane bubbles or oil droplets under different p-T conditions.

Purpose:

Definition of the influencing factors on the rising velocity of methane bubbles rising in artificial seawater as the first step to describe multiphase jet behavior under deep-sea conditions. Experimental results shall be integrated in existing near and far field models to predict the distribution of hydrocarbons in the ocean.

Data Parameters and Units:

- rising velocities (m/s) - diameter (mm) - pressure (MPa) - temperature (°C) - amount of bubbles

Methods:

- video recording of the rising bubbles - semiautomatic evaluation of the rise velocity and particle diameter via an script developed at the Institute of Multiphase Flows (TUHH) This experimental data has been published in the proceedings of the 7th International Symposium on Environmental Hydraulics (2014). Title of publication: A new high-pressure laboratory setup for the investigation of deep-sea oil spill scenarios under in-situ conditions. ISBN: 978-981-07-8047-0.

Instruments:

- high pressure tank with integrated jet-module - high speed camera to record the rising particles
