Numerical Simulation and Analysis of the Coupled Flow Field of Multiple Propeller-Type Current-Meters Based on CFD
Abstract— The standard k-ε turbulence model in computational fluid dynamics software FLUENT was used,
and the coupled flow field of multiple propeller-type current-meters was simulated numerically, properties of
the coupled flow field under different distances between each two current-meters and different initial flow
velocity were found out. Results show that: the interaction on flow field of the adjacent current-meters causes
the bimodal trend of flow velocity which means flow velocity decreases rapidly after the peak; the rod
deformed in the flow field along flow direction and make the deflection of axes of current-meters happen,
which cause the deviation between measured velocity and actual velocity, and this deviation became larger
with the flow velocity increases. The detailed information of flow field is obtained in this paper, which
provides theoretical evidence to development and actual measurement of propeller-type current-meter.
