Transient Fluid Forces on a Rigid Circular Cylinder Subjected to Small Amplitude Motions
(The American Society of Mechanical Engineers (ASME), 2008)The present paper treats the transient fluid forces experienced by a rigid circular cylinder moving along a radial line in a fluid initially at rest. The body is subjected to a rapid ... -
Godunov’s Method for Simulatinons of Fluid-Structure Interaction in Piping Systems
(The American Society of Mechanical Engineers (ASME), 2008)Constant coefficient one-dimensional linear hyperbolic systems of partial differential equations (PDEs) are often used for description of fluid-structure interaction (FSI) phenomena during transient ... -
Crack Growth Under Moving Temperature Field by the Example of Circumferential Crack in Steel Cylinder Specimen

Thermal Simulation of an Arbitrary Residual Stress Field in a Fully or Partially Autofrettaged Thick-Walled Spherical Pressure Vessel
(The American Society of Mechanical Engineers (ASME), 2008)The equivalent thermal load was previously shown to be the only feasible method by which the residual stresses due to autofrettage and its redistribution, as a result of cracking, can be ... -
Pressure Vessels With Reinforcing Space-Filling Skeletons
(The American Society of Mechanical Engineers (ASME), 2008)Light-weight high pressure vessels are recently in demand mainly because of the need to replace gasoline engines with hydrogen fuel cells. One of the main problems delaying this transition is ... -
Applying Neural Networks to the Solution of the Inverse Heat Conduction Problem in a Gun Barrel
(The American Society of Mechanical Engineers (ASME), 2008)The primary cause of gun barrel erosion is the heat generated by the shell as its travels along the barrel. Therefore, calculating the heat flux input to the gun bore is very important when ... -
Application of Models for Laminar to Turbulent Transition to Flow Around a Circular Cylinder
(The American Society of Mechanical Engineers (ASME), 2008)In many technical fields, for example, in heat exchanger design, circular cylinders are involved in fluid structure interaction problems. Therefore, correct fluid forces are needed. Direct numerical ... -
