Properties of the laminar-turbulent transition in a mixing layer by the low-frequency disturbance (Effect of the anti-symmetrical disturbance)

open access: yesJournal of Fluid Science and Technology, 2014
The laminar-turbulent transition of a mixing layer excited by oscillating flat plates at an exit of a two-dimensional nozzle was experimentally investigated. The mixing layer was formed between the jet issued from the nozzle and the surrounding quiescent

Soil mixing with organic matter amendment improves Albic soil physicochemical properties and crop yield in Heilongjiang province, China.

open access: yesPLoS ONE, 2020
Crop productivity in Albic soil is poor, owing to poor soil physicochemical properties. Mixing of Aw layers, representing Albic soil, with B layers, could improve the physicochemical properties of Albic soil, which is characterized by poor humus on the ...

Vertical mixing layer development [PDF]

open access: yesEuropean Journal of Mechanics - B/Fluids, 2014
a b s t r a c t A new generation of current and wave testing tanks is required to simulate more realistic sea conditions at larger scales. One means of producing a current is by using groups of impellers arranged around the perimeter of a circular tank. Each propeller produces a single flow velocity which may be different to its neighbours.
