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.

Available in PDF, EPUB and Kindle. Book excerpt: The results of an experimental investigation of the effects of a flexible boundary on pressure drop in turbulent flow in a pipe are reported. A test section was made by casting a highly compliant, elastic gel between two concentric pipes. The inner pipe was then removed leaving a flexible boundary for flow studies. Fluid was caused to flow through the test section and pressure drop measurements were recorded at Reynolds numbers ranging from 1800 to 15,200. The pressure drop across the flexible boundary was found to be greater than that encountered in a similar section with a solid boundary. Below Re 13,500, this increase can be explained either in terms of effective wall roughness or by an effect of the flexible boundary on turbulence. Above Re 13,500, the data indicate a pressure drop increase due to the effects of the flexible boundary. (Author).

This book was released on 1983 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using laser-doppler anemometry and calibrated preston tubes, experiments were performed in water (80 degrees c, 0.6 mpa) to obtain information on the distributions of wall shear stresses, mean axial velocities and turbulence intensities for fully developed adiabatic flow through a six rod bundle at a reynolds number of 5x10 sup(5). the rods were arranged in a square array with a pitch to diameter ratio of 1.15 and a wall-distance to diameter ratio of 0.62. a survey of the literature is presented which suggests that the fundamental mechanics of turbulent subchannel flows are yet to be completely understood. present results show large wall shear stress variations (+- 40 percent) around the rods. friction factors based on measured local parameters in the central subchannels were found to be 15 percent larger than the corresponding values for smooth pipes. the skewed wall shear stress profiles along with the deformed constant-velocity lines suggest the presence of rather strong secondary flows in the corner subchannels. however, their effects appear to be minimal in the wall and central subchannels. mean axial velocity and turbulence intensity profiles across the gaps and along mid-gap planes are presented and their interesting features are pointed out. the core flow in the central subchannel appears to be similar to pipe flow, but in the gap regions much higher turbulence intensities are encountered. the data suggest that, compared to triangular array bundles, square arrays produce higher turbulence intensities at the gaps. also, the present results tend to favour the school of thought claiming that turbulent mixing between adjacent subchannels is rather insensitive to gap size.
Book Synopsis Experimental Investigation of Influence of Turbulence of Flow on Heat Exchange During Motion of Air in Pipes by : I. T. Shvets

This book was released on 1967 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments were conducted on study of heat exchange during motion of air in relatively short pipes in range of Reynolds numbers 1,000 to 50,000 with consideration of initial turbulence of flow. Experimental material was a segment of EYalT steel seamless pipe with internal diameter 51mm, wall thickness 1.5mm, and 4,000mm length. Conditions for experiment are described in detail. Results of experiments were processed to obtain dependence of average and local Nusselt number on Reynolds number at different sections of pipe for different magnitudes of Karman number.

This book was released on 1966 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: The boundary layer research facility utilizing glycerine with its high viscosity was constructed to permit detailed experimental investigation of the viscous sublayer. In this facility at a pipe Reynolds number of 8700 the sublayer thickness was 0.110 in. which is sufficiently thick to allow detailed investigation in a region that occupies the innermost few thousandths of an inch in most typical air and water flows. Detailed measurements of the streamwise fluctuating velocities with hot-film anemometers were obtained within the viscous sublayer as well as in the transition region between the linear and logarithmic mean velocity profiles. These data were used to form the space-time correlation function of the streamwise fluctuating velocities. From these data an eigen-function expansion of the streamwise fluctuating velocity was obtained which was used to infer the dominant large scale structure of the flow in the wall region. (Author).
