Abstract: The characteristics of cut‐throat flow measuring flumes are examined with special attention to scale effects and the transition submergence at which the flow regime changes from undrowned to drowned. Three flumes were ...

Abstract: A hydraulic model study of an existing sloping crest Crump weir is described. Two models of scales 1:10 and 1:3 were tested. At relatively large heads, the structure behaves as one half of a flat‐V Crump weir with the same ...

Abstract: The effects of streamwise acceleration on a two-dimensional heated boundary layer undergoing natural laminar-turbulent transition were investigated with detailed measurements of momentum and thermal ...

Abstract: Attempting to understand the mechanisms of momentum and thermal transports in transitional boundary layers has resulted in the use of conditional sampling to separate the flow into turbulent and ...

Abstract: A conditional sampling technique was employed to separate the turbulent and nonturbulent parts of accelerated boundary layers undergoing laminar-turbulent transition on a uniformly heated flat ...

Abstract: The conditionally sampled fluctuation quantities of nonaccelerating and accelerating heated transitional boundary layers were analyzed. The results indicated that the values of u′, υ′, uv , and ...

Abstract: Earthquake-induced damage to structural components and spray-applied fire-resistive material (SFRM) in steel gravity frame beam-column connection regions can impact connection performance during an ensuing fire. Bolted ...

Abstract: In high temperature solar energy applications highly concentrating optical systems, such as, e.g., parabolic dishes, achieve typical radiation flux densities >2 MW/m2 . In order to investigate ...

Abstract: The trapezoidal free overfall is analyzed by the one‐dimensional momentum equation, including an assumed pressure distribution at the brink. The pressure distribution is based on previous measurements in rectangular and ...
