The effectiveness of a three-dimensional mixed-flow turbulence model describing airspeed and temperature distribution in a laboratory scale slot-ventilated chamber was evaluated. Airspeed and temperature profiles were investigated near the inlet jet region and along an axial line extending from the inlet. The observed jet-floor impingement location was accurately predicted^ with a maximum diffe...

We review the gamma-ray variability properties of AGN with a jet not directly pointing at the observer, i.e. Misaligned AGN. This class is mainly populated by nearby low power radio galaxies (i.e. FRIs). The high power radio sources (i.e. FRIIs) are indeed rare in the GeV sky. Our Fermi-LAT inspection of 4 years of data reveals different temporal behaviors, supporting the idea that beaming/jet ...

We present sensitive, high-resolution λ21-cm VLBA+VLA observations of the radio jet and nuclear HI absorption in NGC 4151. The 25-mas (1.6-pc) resolution continuum image reveals a highly collimated radio jet, underlying the discrete components seen previously with MER-LIN and the VLA. Spatially and kinematically complex HI absorption is detected against the whole 3-pc extent of the continuum co...

In the developing flow region of a plunging jet, the verynear field (i.e. (x-x1)/d1 < 5) is strongly affected by the entrapment process at the impingement. New quantitative results show that, although the distributions of void fraction and mean velocity have smooth shapes, the flow is highly fluctuating and unstable. At a given location in the mixing layer, the probability distribution function...

A jet with a width of 2.5% the chord length is placed on a NACA0012 airfoil’s upper surface simulating the blowing and suction control under Re = 5 × 105 and angle-of-attack 18-deg conditions. Nearly 300 numerical simulations are conducted over a range of parameters (jet location, amplitude, and angle). The physical mechanisms that govern suction and blowing flow control are determined and anal...

Experimental measurements and flow visualization of synthetic jets and continuous jets with matched Reynolds numbers are described. Although they have the same profile shape, synthetic jets are wider and slower than matched continuous jets. The synthetic jets are examined at higher Reynolds numbers than previously studied and over a large range of dimensionless stroke lengths. Nomenclature b cr...

We have examined the Ne/O and Fe/O characteristics of large solar energetic particle (SEP) events at ion energy range 3–40 MeV nucleon?1 during cycles 23 24. In each cycle, activity displays an ?3 yr rising phase a longer declining phase. While Fe-poor only appeared in cycle 23, properties Fe-rich were similar phases both cycles. Also, very few seen addition, data corona, wind, SEP consistently...

We investigated the effect of a photovoltaic field generated on surface iron-doped lithium niobate crystals sessile droplets ferroelectric nematic liquid crystalline and standard material present this surface. When such an assembly is illuminated with laser beam, wide range dynamic phenomena are initiated. Droplets located outside spot dragged in direction area, while inside region tend to brid...
