摘要:

With the assumptions of a heat insulated body, a Prandtl number of unity and a linear temperature‐viscosity relation the axisymmetric equations governing a given high‐speed compressible flow are reduced to the equations describing an incompressible two‐dimensional flow past a flat plate with a determinable main stream and normal wall velocity distribution. The results are applied to the supersonic flows over a cone with wall velocities proportional (i) to the first power and (ii) to the inverse‐half‐power of distance along a generator when the resulting incompressible flows are known. Also the flow near the tip of a general slender body of revolution in supersonic flow with constant wall velocity is obtained by solving numerically the equations of the correlated incompressible flow. It is also shown that, if the assumption of an insulated body is discarded, a given high‐speed compressible flow may still be correlated with a determinable low‐speed compressible flow.

摘要:

Consideration is given to the combined forced and free convection flow and heat transfer about a nonisothermal body subjected to a nonuniform free stream velocity. Similar solutions for the laminar boundary layer equations are found to exist when the free stream velocity and surface temperature vary respectively asxmandx2m−1. The parameter controlling the relative importance of the free and forced convection is Gr/Re2. A flow separation phenomenon may occur when the forced and free convection act in opposite directions. Extensive numerical solutions of the transformed boundary layer equations have been carried out for the cases of uniform wall temperature and uniform wall heat flux for a Prandtl number of 0.7 (gases) over a wide range of values of Gr/Re2. Results are reported for the heat transfer, shear stress, and velocity and temperature fields. Criteria are given for cataloging flows as purely forced, purely free, and mixed.

摘要:

Under pressure of sufficient magnitude, a metal such as copper can be considered to be an inviscid compressible fluid specified by an experimentally determined Hugoniot curve. This paper indicates the calculations necessary to solve the elementary problem of flow of an arbitrary fluid around an infinite wedge. The results are displayed in the form of graphs. A graphical solution is indicated for a problem involving impact of a conical projectile with a target. Agreement has been obtained between the theoretical and experimental results.
