Flow visualization study of the effect of injection hole geometry on an inclined jet in crossflow [PDF]

A flow visualization was studied by using neutrally buoyant, helium-filled soap bubbles, to determine the effect of injection hole geometry on the trajectory of an air jet in a crossflow and to investigate the mechanisms involved in jet deflection ...

Designing Physical Unclonable Functions From Optically Active Materials

Advanced Materials, EarlyView.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Iterative Solution for Ideal Fluid Jets

Journal of Hydraulic Engineering, 2013
Free jets are important flow phenomena from outflow structures of dams and reservoirs. The basic case of jet flow originates from a free overfall with upstream critical flow conditions and a fully ventilated nappe. In this paper, a two-dimensional potential flow model has been developed.
