This book was released on 1979 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous investigations of distributed-roughness boundary-layer trips indicated that they are superior to spherical-type trips in that equally effective distributed-roughness trips are one-fifth as high and produce substantially smaller flow-field disturbances. The present work has expanded the data base, permitting correlation of distributed roughness tripping data. The correlation thus developed includes a wide range of Reynolds numbers, cone angles, and trip heights. Plots are provided that permit the selection of distributed-roughness trips without the need of boundary-layer solutions.

Boudreau and published by . This book was released on 1978 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research directed toward establishing criteria for distributed roughness-type boundary-layer trips on blunt-slender cones has been conducted in the AEDC/VKF at Mach numbers from 8 to 13. Results indicate that distributed roughness trips are superior to spherical-type trips in that equally effective distributed roughness trips are one-fifth as high and produce substantially smaller flow-field disturbances. Criteria are defined for optimum utilization of distributed roughness trips.

This book was released on 1982 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: New wind tunnel data has been obtained to investigate the effects of tip bluntness and angle of attack on boundary layer transition on slender cones. The rearward displacement of transition due to tip bluntness and the maximum displacement of transition are reasonably well understood and explainable primarily on the basis of a reduction in local Reynolds number due to pressure losses across the bow shock. The rapid forward movement of transition observed on the cone frustum is a mystery and will be studied further in future experiments. The observed rapid movement of transition from the sphere-cone tangency point to the subsonic region of the tip is compatible with stability analysis and has been observed by several experimentalists. The transition movements obtained on the sharp cone at angle of attack were compatible with both theory and other experiments. The movements of transition on blunt cones at angle of attack remains poorly understood. The present results appear reasonable; however, since many different trends have been observed in transition experiments and since there is little guidance available from stability analyses, additional confirmation of these transition trends are needed.

Available in PDF, EPUB and Kindle. Book excerpt: Investigations of the effects of nose blunting on the location of boundary-layer transition on slender cones at supersonic or hypersonic speeds so back 25 years. For some time it was thought that the movement of the transition point was simply due to the reduction in local Reynolds number associated with the loss in total pressure through the bow shock. More recently, it has been shown that variations in the local transition Reynolds number also occur on a blunt cone and that both these effects must be taken into account in explaining the observed movement in transition along the cone frustum. The present investigation was carried out as a demonstration test for the development of a new capability in Hypervelocity Tunnel 9 at the Naval Surface Weapon Center. The objective of this development effort was to raise the Reynolds number at Mach 10 from about 5 x 1000000 per foot to 20 x 1000000 per foot. This was done so that naturally turbulent boundary layers (i.e. without tripping) could be obtained on R/V models. Thus an investigation of boundary layer transition was an appropriate choice for the demonstration test.
