Free surface potential flows past disturbances in a channel are considered. Three different types of disturbance are studied: (i) a submerged obstacle on the bottom of a channel; (ii) a pressure distribution on the free surface; and (iii) an obstruction in the free surface (e.g. a sluice gate or a flat plate). Surface tension is neglected, but gravity is included in the dynamic boundary conditi...

Myanmar and its surrounding areas have complex topography strong tectonic movement, which has always been a challenge to most geoscientists. We used teleseismic tomography study the subsurface velocity structure in this area. present new P-wave tomographic model beneath by inverting 129,788 arrival-time data recorded 372 stations. found an inclined high-velocity subducting plate central Myanmar...

Light-sheet fluorescence microscopy (LSFM) with single light-sheet illumination enables rapid 3Dimaging of living cells. In this paper we show the design, fabrication and characterization a diffractive optical element producing several light sheets along an inclined tube for applications in flow-driven imaging. The element, which is based on multi-focal Fresnel zone plate linear grating, genera...

In this study, nanofluid condensation and MHD flow analysis over an inclined and rotating plate are investigated respectively using Least Square Method (LSM) and numerical method. After presenting the governing equations and solving them by LSM, the accuracy of results is examined by the fourth order Runge-Kutta numerical method. For condensation, modeling results show that the condensate f...

This study experimentally investigates the generation mechanism of a higher-angle lobe which is an acoustic field feature supersonic jet impinging on inclined flat plate. The overall sound pressure level distribution and spectra, conditional averages near schlieren movies, time-averaged wall were obtained for three cases Mach 1.8 ideally expanded jets with plate angles 45°, 22.5°, 10° to downst...
