Methods for computation of flow-driven string dynamics in a pump and residence time

Mathematical Models and Methods in Applied Sciences, 2019
We present methods for computation of flow-driven string dynamics in a pump and related residence time. The string dynamics computations help us understand how the strings carried by a fluid interact with the pump surfaces, including the blades, and get ...

Study of fluid dynamic conditions in the selected static mixers part II‐determination of the residence time distribution

The Canadian Journal of Chemical Engineering, 2017
AbstractThe presented paper is part of the complete description of fluid‐dynamic conditions in the selected static mixers: Koflo and Kenics. The research was also performed for an empty pipe used as a reference state. The scope of work included the analysis of the residence time distribution in the mentioned devices for different Reynolds numbers for ...

Case study comparisons of computational fluid dynamics (CFD) modeling versus tracer testing for determining clearwell residence times in drinking water treatment

Journal of Environmental Engineering and Science, 2006
Computational fluid dynamics (CFD) modeling and full-scale tracer tests (using barium or fluoride) were used to determine the baffle factors of clearwells at three Canadian water treatment facilities (two in Ottawa, Ontario, and one in Peterborough, Ontario). A variety of clearwell baffling configurations and a range of flow rates (35 to 257 MLD) were
