Abstract: This study reexamines past studies of how drag-reducing polymer solutions modify the log-region of a developing turbulent boundary layer (TBL). The classical view was that the polymers modify the intercept constant without ...

Abstract: The authors provide an extensive review of this field, outlining its multidisciplinary history, presenting a stateoftheart review of current methods and applications, a description of the phenomena observed and projections ...

Abstract: Historical use of aqueous film-forming foam (AFFF) has led to widespread contamination of water and soil, due to the high per- and polyfluoroalkyl substance (PFAS) content in AFFF. Due to the high toxicity and environmental ...

Abstract: Through experiments using two-dimensional particle-image velocimetry (PIV), this paper examines the nature of transition in a separation bubble and manipulations of the resultant breakdown to ...

Abstract: Through numerical simulations, this paper examines the nature of instability mechanisms leading to transition in separation bubbles. The results of two direct numerical simulations are presented ...

Abstract: In this paper, transition in a separation bubble is examined through numerical simulation. The flow Reynolds number and streamwise pressure distribution are typical of the conditions encountered ...

Abstract: The development of turbulent spots in a separation bubble under elevated freestream turbulence levels is examined through direct numerical simulation. The flow Reynolds number, freestream turbulence ...

Abstract: A combination of extrapolation and estimation techniques from both prior and current studies has been explored with the goal of developing a method to accurately characterize high-stress amplitude ...

Abstract: The paper presents mid-span measurements for a turbine cascade with active flow control. Steady blowing through an inclined plane wall jet has been used to control the separation characteristics ...
