GRAVITY DRAINAGE OF AN OPEN SPHEROIDAL TANK
ANALES AFAThis study simulates the gravity-driven drainage of an open spheroidal tank. A dimensionless parameter λ is introduced that alters the geometry of the tank but not its volume, generating prolate, spherical, and oblate spheroidal variants. The openings in the tank are obtained by cutting its surface with two symmetrical planes, close to the ends ...

Analysis of Drainage Depth for Pond Water Disposal in Sicanang Village, Medan Belawan
Aquatic Life SciencesMedan Belawan, especially Sicanang Village, is a coastal area suitable for ponds. To replace pond water, the existing water must be drained first, so it's important to assess the land's drainage capability when selecting pond locations.

Venous drainage - gravity or assisted?
Perfusion (United Kingdom), 2011Since the early start of cardiopulmonary bypass, vascular access has been recognized as a main variable for obtaining optimal blood flow during cardiopulmonary bypass. In particular, venous drainage can limit the maximum flow as the wide, low-resistance, collapsible veins are connected with smaller stiff cannulas and tubing.

A New Thermogeomechanical Theory for Gravity Drainage in Steam-Assisted Gravity Drainage
SPE Journal, 2013Summary Oil-sands reservoirs in western Canada hold more than 170 billion bbl of recoverable heavy oil and bitumen representing a significant source of unconventional oil. At in-situ conditions, the majority of this oil has essentially no initial mobility because of its high viscosity, which is typically in the hundreds of thousands to ...

Transactions of the AIME, 1949
Abstract This paper presents a theory for estimating the rate of gravity drainage ofa liquid out of a sand column. Account is taken of the variation inpermeability to the liquid as the saturation in the upper part of the sandbecomes less than 100 pct. The theory is confirmed by previously published

Effect of Dip Angle on Recovery Factor During Free Fall Gravity Drainage and Forced Gravity Drainage
82nd EAGE Annual Conference & Exhibition, 2021Summary Gravity drainage is an effective recovery mechanism in the majority of fractured reservoirs. In this study, the effects of matrix and fracture orientation, and 0–20 degrees’ deviation from vertical alignment on recovery factors were investigated during free fall gravity drainage (FFGD) and forced gravity drainage (FGD).
