This book was released on 1989 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study concerns the ability to achieve good accuracy in missile after body flow predictions based on the Reynolds-averaged Navier-Stokes equations. The problems of numerical accuracy and turbulence modeling are addressed. By employing grids which were cell clustered and which have grid lines aligned with streamlines in shear layers, it was possible to obtain numerically accurate solutions and to obtain solutions at very high nozzle pressure ratios. The effects on turbulence of high Mach numbers and streamline curvature were examined. It was demonstrated that these phenomena have a significant effect on the turbulence and on the global flow characteristics such as base drag. Changes in base drag on the order of +/-20% for some afterbody flows can be attributed to Mach number and curvature effects. A modified form of the k-epsilon turbulence model which gives good accuracy for flows involving high Mach number and streamline curvature is presented. Keywords: Base drag, Turbulence modeling, Computational fluid dynamics, Truncation error estimates.

Book Synopsis A Free-flight Investigation of the Effects of Simulated Sonic Turbojet Exhaust on the Drag of a Boattail Body with Various Jet Sizes from Mach Number 0.87 to 1.50 by : Ralph A. Falanga
Download or read book A Free-flight Investigation of the Effects of Simulated Sonic Turbojet Exhaust on the Drag of a Boattail Body with Various Jet Sizes from Mach Number 0.87 to 1.50 written by Ralph A. Falanga and published by . This book was released on 1955 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three 7.5 degree boattail bodies of revolution with varying base-annulus areas and jet sizes provided with simulated-turbojet-exhaust rocket motors were flight-tested to determine the jet interference effects on drag over a Mach number range from approximately 0.87 to 1.5. The results indicated that in the transonic and low-supersonic speed range the jet caused positive pressure increments on the base and boattail which appreciably reduced the configuration drag from the power-off condition. At the high supersonic speeds, the jet caused positive pressure increments only on the base and resulted in a smaller reduction in body drag from power-off conditions.
