Drilling horizontal wells (HWs) has recently received renewed attentions with the increasing trend in exploitation of tight gas reservoirs. An accurate estimation of productivity of such systems using a numerical simulator is a challenging task, because its 3D simulation requires a fine grid exercise to capture the abrupt variation of fluid and flow parameters around the wellbore. This is ...

Since the invention of laser sources, understanding the interaction between the laser and biological tissues is a subject of great importance because of their medical applications in particular for diagnostic purposes. They recently found a growing interest in the sector of the arboriculture to check the fruits quality in a non-destructive way. In this work, we study the interaction between the ...
Evaluation of COMSOL as a Tool for Pinpointing Moisture Entering Locations From Inside Surface Moisture

The location and nature of the moisture leakages are sometimes difficult to detect. Moreover, the relation between observed inside surface moisture patterns and where the moisture enters the construction is often not clear. The objective of this paper is to investigate inverse modeling techniques as a tool for the detection of moisture leakage locations in building constructions from inside ...

Surface coating can fullfil their function satisfactorily over an extended period of time only if there is a good bond between the concrete substrate and the coating. The most numerous cases of blistering affect the airtight covers of the concrete subjected to negative pressures of humidity from the support. The general objective of this study is the understanding of the blistering phenomenon. ...

This paper will give a short overview of use of COMSOL Multiphysics for analyzing ancient Greek and Roman catapults with the main focus on the energy storing torsion springs. Catapults have been known and used in the Greek and Roman world from around 399 BC and a fully standardized design for powerful torsion catapults emerged around 270 BC, based on one basic factor, the diameter of the torsion ...
