Available in PDF, EPUB and Kindle. Book excerpt: The study of flow induced phenomena at the interface between a solid body and a fluid in contact with it is essential to the understanding of such vital engineering problems as drag, flow noise and other energy dissipation characteristics of turbulent flow. At present, investigations have been made of flow properties near a solid boundary and the results extrapolated to the boundary itself by means of energy and momentum conservation principles. The results of these experiments tend to support the theory; however, the data is sparse and many assumptions and secondary mathematical relations must be used before this can be achieved. In this study shear stress was measured at the wall itself using flush-mounted hot-film anemometers. The purpose was to test two models of the structure of the viscous sublayer. The test apparatus consisted of a pipe four inches in diameter and forty feet long connected to a water reservoir in a closed loop design. The test section was located near the end of the pipe to assure fully developed flow conditions. Fluctuating wall shear stress was measured to determine a model of the viscous sublayer.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Turbulent flow over a wavy wall in a horizontal channel is investigated by experimental and numerical methods. The thorough problem understanding can advance turbulent flow physics knowledge for separating and reattaching flows. Another important consideration is the performance evaluation of mathematical models used in computational fluid dynamics (CFD) codes to predict the flow characteristics. This study explores numerical models because they are critically important to the design and performance evaluation of engineering systems. The experimental data are obtained to provide repository data and more insights into the flow physics considering both the flow development and fully periodic regions. A channel with a wavy bottom wall is considered for this study, and its main characteristic is a value of 10 for the ratio between the wave length and wave amplitude. A high-resolution particle image velocimetry (PIV) system is used to obtain detailed measurements of velocity at Reynolds number of 5040, 8400, 10700 and 13040 in both the developing and fully periodic regions. The numerical simulations are performed with a commercial CFD code using four eddy viscosity turbulence models and three Second-Moment Closure (SMC) turbulence models. This work assessed the predictive accuracy of a total of seven turbulence models. The experimental study covered a lack of data for the flow development within the waves, prior the periodic condition region, and it supported the turbulence models evaluation. The experiments provided features of the flow such as the recirculation regions, Reynolds stresses, and turbulent kinetic energy production at different channel locations. A comprehensive comparison between models and experimental data revealed a significant dependency on the turbulence model formulation and on the wall treatment selection for the flow development and fully periodic regions predictions.
