Pressure wave propagation in Managed Pressure Drilling- model comparison with real life data
Berg, Christian; Stakvik, Jon Åge; Lie, Bernt; Vågsæther, Knut; Kaasa, Glenn-Ole (Peer reviewed; Journal article, 2019)Drilling for oil and gas is a complex process, involving pumping of fluid through kilometers of pipes. Even though the drilling fluid has a high speed of sound (˜1000 m/s), the large lengths involved make pressure wave ... -
Use of Orthogonal Collocation Method for a Dynamic Model of the Flow in a Prismatic Open Channel: For Estimation Purposes
Jinasena, Asanthi; Kaasa, Glenn-Ole; Sharma, Roshan (Journal article; Peer reviewed, 2017)The modeling and simulation of free surface flows are complex and challenging. Especially, the open channel hydraulics are often modeled by the well–known and efficient Saint–Venant equations. The possibility of efficiently ...
