Abstract: The influence of residual stress on fatigue crack growth was experimentally and analytically investigated for surface cracks. Fatigue tests were performed on straight pipes of low-carbon steel ...

Abstract: This paper presents an analysis of a class of latent heat storage systems (LHSS). The analysis is based on a lumped model (the basic model) that allows a broad class of LHSSs to be completely ...

Abstract: Application of optimal control system to thermal power plants is introduced. The suggested system consists of the conventional PID controllers and the control computer. It has been successfully ...

Abstract: Nondestructive measurements of residual stresses were successfully attempted by the acoustoelastic technique on butt-welded joints of a carbon steel for nuclear piping. Usefulness of the technique ...

Abstract: This paper presents an analysis of a class of latent thermal energy storage (LTES) system. The analysis is based on a simplified model that allows the system performance to be evaluated in ...

Abstract: A one-dimensional two-fluid model has been used to study the centrifugal pump head degradation phenomena and to analyze the gas-liquid interaction within the pump impeller under high pressure, ...

Abstract: This paper describes a synchronous controller for high-productivity NC gear grinding machines that use a screw-shaped CBN wheel of multithread. The authors developed a high-precision controller ...

Abstract: The effect of fuel injection timing relative to ignition timing on natural gas direct-injection combustion was studied by using a rapid compression machine (RCM). The ignition timing was fixed ...

Abstract: The International Fusion Materials Irradiation Facility (IFMIF) is a D+–Li neutron source aimed at producing an intense high energy neutron flux (2 MW/m2) for testing candidate fusion reactor ...
