an analytical model for velocity distribution in transition zone for channel flows over inflexible submerged vegetation
the estimation of velocity distribution plays a major role in the hydrodynamics of vegetated streams or rivers of extensive natural floodplains. the velocity profile in vegetated channels can be divided into three zones: uniform zone which is close to bed with uniform velocity distribution, logarithmic zone which involves the main channel with no vegetive cover and the transition zone that is a...

در این پایان نامه روش جدیدی مبتنی بر روش حل معادلات دیفرانسیل پارهای بر اساس روش توابع پایه برای حل مسایل ارتعاش اجباری واستاتیک تیرها و صفحات لایه ای ارایه شده است که می توان تفاوت این روش با روش های متداول توابع پایه را در استفاده از توابع هموار در ارضاء معادلات حاکم و شرایط مرزی دانست. در روش ارایه شده در این پایاننامه از معادله تعادل به عنوان معادله حاکم بر رفتار سیستم استفاده شده است که مو...
15 صفحه اولAn Analytical Model for the Distributions of Velocity and Discharge in Compound Channels with Submerged Vegetation
Based on the momentum transfer theory, an analytical model is proposed for the velocity and discharge distributions in compound channels with submerged vegetation on the floodplain. The partially vegetated channel was divided into three sub-regions, i.e. the main channel region, the floodplain region with submerged vegetation and the floodplain region without vegetation. For each region, the fo...
متن کاملLarge Eddy Simulation of Fully-Developed Turbulent Flow Through Submerged Vegetation
Large Eddy Simulations (LES) are performed for an open channel flow through submerged vegetation with a water depth (h) to plant height (hp) ratio of h/hp=1.5 according to the experimental configuration of Fairbanks and Diplas (1998). Fairbanks and Diplas measured longitudinal and vertical velocities as well as turbulence intensities along several verticals in the flow and the data are used for...
متن کاملDYE JET VELOCITY DISTRIBUTION MEASUREMENTS USING PHOTOTHERMAL DEFLECTION SPECTROSCOPY
We demonstrate that photothermal deflection spectroscopy can be used to measure velocity distributions in dye jets. Such measurements are useful in determining the quality of flow in dye jets, The quality of jets is very important for a stable and naanow linewidth operation of dye lasers
