Consolidation Solutions of a Saturated Porothermoelastic Hollow Cylinder with Infinite Length

Consolidation Solutions of a Saturated Porothermoelastic Hollow Cylinder with Infinite Length

An analytical method is derived for the thermal consolidation of a saturated, porous, hollow cylinder with infinite length. The solutions in Laplace transform space are first obtained and then numerically inverted by Stehfest method. Two cases of boundary conditions are considered. First, variable thermal loadings are applied on the inner and outer pervious lateral surfaces of the hollow cylind...

Eect of Rotation on Thermoelastic Waves with Green-Naghdi Theory in a Homogeneous Isotropic Hollow Cylinder

Continuous Heating of a Hollow Cylinder*

7. The essence of the method of characteristics is the following. Suppose the flow is to be determined in the channel of Fig. 4 and the flow is known up to the line I. Select points A and B on line I. At these points the velocity, the direction of flow, etc., is known. Thus characteristics Ca and Cb can be drawn. Equation (17) used along the two different characteristics gives two equations for...

Mathematical Modeling of Thermoelastic State of a Thick Hollow Cylinder with Nonhomogeneous Material Properties

The object of the present paper is to study heat conduction and thermal stresses in a hollow cylinder with nonhomogeneous material properties. The cylinder is subjected to sectional heating at the curved surface. All the material properties except for Poisson’s ratio and density are assumed to be given by a simple power law in the axial direction. A solution of the two-dimensional heat conducti...

Reluctance Machine for a Hollow Cylinder Flywheel

A hollow cylinder flywheel rotor with a novel outer rotor switched reluctance machine (SRM) mounted on the interior rim is presented, with measurements, numerical analysis and analytical models. Practical experiences from the construction process are also discussed. The flywheel rotor does not have a shaft and spokes and is predicted to store 181 Wh/kg at ultimate tensile strength (UTS) accordi...
