1 mm is shown in Fig. 5.3b. As pressure decreases along the rise path, the rise velocity is steadily increasing.
To account for the aforementioned effects experimentally, a setup with adjustable pressure is required that enables the investigation of rising gas-saturated crude
oil droplets over an extended period of time. For this purpose, the high-pressure cell
with the hourglass-shaped glass tube that has been used for the investigation of dead
oil droplets before is extended in such a way as to allow for saturation of the crude
oil with a gas at a defined saturation pressure. LSC oil is brought into contact with
Fig. 5.3 Modeling results for the rise behavior of a methane-saturated LSC oil droplet through
1500 m of water column: (a) increasing droplet diameter d p , depicted in a dimensionless form by
dividing it by its initial value d p, 0 ; decreasing mean droplet density ρ p , depicted in a dimensionless
form by dividing it by its initial value ρ p, 0 ; and increasing gas void fraction ϵ dependent on the rise
height z; (b) rise velocity evolution of a droplet with an initial diameter of 1 mm dependent on the
rise height z (Pesch et al. 2018)
