PIV and CFD measurements of internal velocity in a forming drop in a liquid-liquid system

Timgren, Anna; Trägårdh, Gun; Trägårdh, Christian

A PIV method has been used to determine the internal motion in an oil drop during formation and to validate a numerical simulation of the drop formation process. The PIV system included a microscope attached to the camera, which gave a focal depth of 50 µm and a possibility to measure the velocity i...

Model-Based Control and Optimization of Large Scale Physical Systems - Challenges in Reservoir Engineering

Van den Hof, P.M.J.; Jansen, J.D.; Van Essen, G.M.; Bosgra, O.H.

Due to urgent needs to increase efficiency in oil recovery from subsurface reservoirs new technology is developed that allows more detailed sensing and actuation of multiphase flow properties in oil reservoirs. One of the examples is the controlled injection of water through injection wells with the...

CFD modelling of drop formation in a liquid-liquid system

Timgren, Anna; Trägårdh, Gun; Trägårdh, Christian

The formation of an oil drop from a single capillary in a continuous phase flowing perpendicular to the capillary opening has been studied numerically. The shear stress at the interface of the forming drop, the angular velocity inside the drop and the pressure field around the drop have been determi...
