Reference number : GC-2017-Q4-00965, amendment number : , agreement type : G, recipient legal name : Lacey, Jay (Université de Sherbrooke), recipient country : CA, recipient province : nan, recipient city : Quebec|Québec, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Air entrainment is a common concern in a number of water resource infrastructures. Water treatment facilities_x000D_
use bubbles (entrained air) to transfer gases such as ozone, oxygen, air, and carbon dioxide into water. Bubbles_x000D_
are also used in grit removal chambers to suspend light solids, while allowing heavier solids (grit) to settle out_x000D_
for removal. Modeling entrained air and sediment accurately is difficult mainly due to problems of properly_x000D_
defining the bubble geometry and the complex interactions that occur between bubbles, sediment and water._x000D_
NHC currently has an interest in applying OpenFOAM for projects involving air entrainment and sediment_x000D_
transport._x000D_
The principal objective of the proposed project is to demonstrate the successful implementation of bubble_x000D_
and sediment models in the open-source computational fluid dynamics (CFD) software OpenFOAM based on_x000D_
an open-channel flow case study. The secondary objective is to develop a simple methodology for_x000D_
incorporating OpenFOAM in NHC's day-to-day workflows which takes advantage of the developed air_x000D_
entrainment and sediment models._x000D_
This collaboration between NHC and the Université de Sherbrooke (UdeS) will provide insights into how_x000D_
OpenFOAM can be effectively employed for complex hydrotechnical projects involving air and sediment. The_x000D_
knowledge gained will enable NHC to bid on previously unattainable projects and allow NHC to be more_x000D_
competitive in its bid thus promoting its future viability. NHC will gain a technical advantage by using an_x000D_
open-source platform over other companies who depend on commercial software and excessive licensing fees._x000D_
Assuring the competitiveness of Canadian owned companies like NHC is thus in the interest of Canada and_x000D_
