Turbulent Boundary Layer on a Yawed Cone in a Supersonic Stream
Author: Willis H. Braun
Publisher:
ISBN:
Category : Aerodynamics, Supersonic
Languages : en
Pages : 28
Book Description
The momentum integral equations are derived for the boundary layer on an arbitrary curved surface, using a streamline coordinate system. Computations of the turbulent boundary layer on a slightly yawed cone are made for a Prandtl number of 0.729, wall to free-stream temperature ratios of 1/2, 1, and 2, and Mach numbers from 1 to 4. Deflection of the fluid in the boundary layer from outer stream direction, local friction coefficient, displacement surface, lift coefficient, and pitching-moment coefficient are presented.

Investigation of Statistical Nature of Fatigue Properties
Author: E. Epremian
Publisher:
ISBN:
Category : Iron
Languages : en
Pages : 746
Book Description
Extensive fatigue tests were made on annealed Armco iron and plain carbon and alloy steels heat-treated to different strengths and microstructures. Statistics of fatigue-fracture curves and endurance limits were determined from the experimental data obtained and, for various other materials, from a survey of literature. The results were analyzed to show the relative effects of various metallurgical factors on the statistical nature of fatigue properties. Other phases of the problem studied include: dependence of statistical variation in fatigue life on stress level in the fracture range, statistics for location of crack initiation, size effect, understressing effect, and the form and method of plotting the S-N diagram.

Calorimetric Determination of Constant-pressure Specific Heats of Carbon Dioxide at Elevated Pressures and Temperatures
Author: Virgil E. Schrock
Publisher:
ISBN:
Category : Aerodynamic load
Languages : en
Pages : 678
Book Description
The constant-pressure specific heat of carbon dioxide has been measured over the range of temperatures and pressures from ambient condtions to 1000 pounds per square inch gage and 1000 degrees F using a steady-flow calorimeter operated on an open cycle. It appears that the apparatus as used in this determination will yield values with a probable error of 0.5 percent at the highest temperature level considered. The results of these tests check the widely accepted spectroscopic data within 1 percent. The values at elevated pressure are in reasonable agreement with those derived from the zero-pressure spectroscopic values and the application of the Beattie-Bridgeman equation of state. Only very limited calorimetric data are available in the literature, but substantial agreement exists with those considered reliable.
