Prediction of the radiated sound power from a fluid-loaded finite cylinder using the surface contribution method
Based on acoustic radiation modes, the surface contribution method has been developed to predict the surface contributions to the radiated sound power from a vibrating structure. In this work, the surface contribution method is used to identify the sound field on a vibrating structure submerged in a heavy fluid. It was recently found that surface contribution method was not able to predict the ...

غزالا همایندها را به صورت ترکیبی از دو یا چند واژه که همواره در متون مختلف زبان ها همراه با هم می آیند تعریف می نماید. از دیدگاه او روند رو به رشد میل به ترجمه ی همایندها در مطالعات ترجمه، به دلیل اهمیت آنها در انسجام ساختار زبان است. این پایان نامه اساسا به ترجمه ی همایندها منحصر شده است. هدف آن بررسی کاربرد راهکارهای غزالا در مورد ترجمه ی همایندها از انگلیسی به فارسی است. هدف دیگر آن یافتن پر...
15 صفحه اولAerodynamic Loads on External Stores: A Review of Experimental Data and Method of Prediction
A survey has been made of the available literature on the aerodynamic loads associated with the external carriage of pylon-mounted stores adjacent to wing-fuselage combinations. The existing methods for estimating the store/pylon loads at both subsonic and supersonic speeds are reviewed with some indication of their accuracy, range of validity and the extent to which they have been verified exp...
متن کاملComputation of Vortex Shedding and Radiated Sound for a Circular Cylinder
The Lighthill acoustic analogy approach combined with Reynolds-averaged Navier Stokes is used to predict the sound generated by unsteady viscous ow past a circular cylinder assuming a correlation length of ten cylinder diameters. The twodimensional unsteady ow eld is computed using two NavierStokes codes at a low Mach number over a range of Reynolds numbers from 100 to 5 million. Both laminar o...
متن کاملPrediction of radiated sound power from vibrating structures using the surface contribution method
A common measure for near-field acoustic energy of a vibrating structure is the acoustic intensity, which usually has positive and negative values that correspond to energy sources and sinks on the surface of the radiating structure. Sound from source and sink areas partially cancel each other and only a fraction of the near-field acoustic energy reaches the far-field. In this paper, an alterna...
