We present an experimental investigation of the flow structure in near wake a NACA0012 airfoil plunging sinusoidally at chord Reynolds number Re = 20 000 and for wide range reduced frequency k Strouhal based on peak-to-peak amplitude St . Estimated mean thrust coefficients using fluctuating velocity fields confirm 2 dependence as well significant effect ? 1. Generally, time-averaged quantities ...

We consider isotropic and monochromatic photon emissions from equatorial emitters moving along future-directed timelike geodesics in the near-horizon extremal Kerr (NHEK) near-extremal (near-NHEK) regions, to asymptotic infinity. obtain numerical results for escaping probability (PEP) derive analytical expressions maximum observable blueshift (MOB) of photons, both depending on emission radius ...

Green water events may present different features in the initial stage of interaction with deck a structure. It is therefore important to investigate evolution types green water, since not all interact at same time. In this paper, three (dam-break, plunging-dam-break, and hammer-fist) are studied. The surface elevations volumes over consecutive events, generated by incident [wave trains wave fl...

the term “ranula” is used to describe a diffuse swelling in the floor of the mouth caused by either a mucous extravasation or, less commonly, a mucous retention cyst derived from the major sublingual or submandibular salivary glands. the most common presentation of ranula is a painless, slowgrowing, soft, and movable mass located in the floor of the mouth. ranula may be simple or plunging. simp...
