Based on a recently published theoretical model, in this work we experimentally studied the problem of gravity water drainage due to continuous steam injection into an elliptical porous chamber made glass beads and embedded metallic, quasi-2D, massive cold slab. This configuration mimics process condensation for given time period during growth stage steam-assisted (SAGD) process, method used re...

BACKGROUND Heart transplantation in patients supported with ventricular assist devices (VADs) entails a high risk of injury at resternotomy. Prior femorofemoral bypass is the preferred approach in these patients, but poor venous drainage may restrict arterial flow rate. PATIENTS AND METHODS We compared bypass parameters, transfusion requirements and postoperative outcome in 33 consecutive pat...

Abstract Currently, the reservoir heterogeneity is a serious challenge for developing oil sands with SAGD method. Nexen’s Long Lake project reported that breccia interlayer was widely distributed in lower and middle part of reservoir, impeding steam chamber expansion heated drainage. In this paper, two physical experiments were conducted to study impact on development production performance. Th...

The lubrication form of the equations governing the flow of a thin liquid film on a horizontal right circular cylinder is derived. The equations are discretized and solved numerically using an alternating-direction implicit algorithm. Simulations demonstrate that the transition from a uniform coating to a final configuration of distinct drops follows a similar evolution for a wide range of cyli...
