The radial symmetric motion problem was examined for a spherical shell composed of a class of imperfect incompressible hyper_elastic materials, in which the materials may be viewed as the homogeneous incompressible isotropic neo_Hookean material with radial perturbations.
The finite differencemethod (FDM) is served here to solve these steady and unsteady Navier-Stokesequations for two-dimensional and incompressible fluids.
This paper points out that the thermal and ablative problems of the shield can be solved solely with the coolant flow only under one-dimensional incompressible or steady condition.
For Blatz-Ko and harmonic compressible materials as well as Mooney incompressible material, the influence of the surface hydrostatic pressure on the critical buckling condition is discussed in detail
In a previous paper[1], a theoretical analysis has been presented to the heat-transfer coefficient for laminar boundary layer flow in the entrance region of a circular tube. This is a succeeding one based on Karman's method of approach, to attack the entrance effect on flow-friction behavior of an isothermal boundary layer flow of incompressible fluid. The family of climensionless velocity profiles is well defined by eq. (3) and (4). The predicted friction coefficients from eq. (17) or (19), eq. (23),...
In this paper, a method of calculation of heat-transfer rate for blunt-bodies in the case of hypersonic turbulent boundary-layer is presented. In order to transform the compressible and axisymmetrical turbulent boundary-layer flow to an incompressible and two-dimensional turbulent boundary-layer flow, the Mager - - Mangier transformation has been applied. According to the characteristics of hypersonic, turbulent boundary-layer with favourable pressure gradient, the classical single-parameter represent...
In this paper we consider two cases of finite-amplitude shearing oscillations of a thick-walled cylindrical tube made of elastic incompressible material——the rotatory and longitudinal shearing oscillations. For the Mooney material both cases are reduced to a linear partial differential equation solvable by the Fourier method. The solution of the initial-boundary problem for the case of free inner surface and clamped outer surface is given.
