Improving flow patterns in a large drinking water reservoir - Making retrofit decisions
Quantifying flow velocities
A large water reservoir was modeled using CFD to improve water quality. Non-uniform discharge, dead zones and partly long residence time caused the deterioration of the water quality. Possible structural measures were evaluated to improve the general flow behaviour in the reservoir.
- Original flow pattern contained large dead (stagnant) zones
- Non-uniform hydraulic residence time was observed
- Implementation of an internal wall resulted in positive impact on the flow pattern
