And Performance

The study on the mechanism and performance of the mechanical seals in reactor coolant pumps (RCPs) is very important for the safe operations of pressurized water reactor power plants. By exploring the operating mechanism of the first seal of the hydrostatic mechanical seal in RCPs, an analytical fluid–solid strong-interaction model of the seal is proposed in this article. The model holds that the mechanical deformations of the seal assembly are dominated by the deflections of the seal rings, and this idea is demonstrated by the numerical simulation result of a fluid–solid interaction (FSI) model. Using the analytical FSI model, the regularity that the leakage rate of the first seal varies with the differential pressure in a RCP is obtained, and compared with the operational data, which is used to verify the model. Based on the understanding of the reliability of the seal, a dimensionless parameter Λ that acts as an attribute to the reliability is proposed in this article. Using the analytical FSI model and Λ as the optimization algorithm and optimization object, respectively, the optimum designs about the seal faceplateconfigurations are performed. Also, the specific optimization conclusions are given simultaneously.

The hypothesis of the new stable heavy hadrons existence is proposed which follows from Cosmic rays physics indirect data. It is shown that the hypothesis does not contradict Cosmochemical data, Cosmological test and the restrictions on New Physics effects. The conclusion is based on the most important property of the new hadrons — repulsion strong interaction with nucleons at large distance asymptote. This effect is substantiated theoretically in the framework of the low-energy hadron interaction model. Some extensions of Standard Model is considered where new stable and metastable quarks appear.

The Doplicher–Fredenhagen–Roberts (DFR) framework for noncommutative (NC) space–times is considered as an alternative approach to describe the physics of quantum gravity, for instance. In this formalism, the NC parameter, i.e. [Formula: see text], is promoted to a coordinate of a new extended space–time. Consequently, we have field theory in a space–time with spatial extra-dimensions. This new coordinate has a canonical momentum associated, where the effects of a new physics can emerge in the fields propagation along the extra-dimension. In this paper, we introduce the gauge invariance in the DFR NC space–time by the composite symmetry [Formula: see text]. We present the non-Abelian gauge symmetry in DFR formalism and the consequences of this symmetry in the presence of such extra-dimension. The gauge symmetry in this DFR scenario can reveal new gauge fields attached to [Formula: see text]-extra-dimension. As application, we construct a unification of Strong Interaction with the electromagnetism and a Higgs model to give masses to the NC bosons. We estimate their masses by using some experimental constraints of QCD.

The spinor strong interaction model recently proposed to account for the meson spectra is extended to include interaction with external gauge fields. An action integral is constructed and a restricted variational principle is employed to reproduce the earlier basic meson equations. In establishing U(1) gauge invariance, the so-called U(1) problem, the absence of pseudoscalar singlet mesons that do not decay strongly, is naturally resolved. SU(2)× U(1) or SO(3) gauge invariance leads to that pseudoscalar isodoublet or isotriplet mesons can generate masses of the gauge bosons without recourse to the unobserved Higgs bosons of the standard electroweak model. The gauge boson masses relate to the linear confinement potential constant of pseudoscalar mesons. The spinor strong interaction model is quantized in a macroscopic approximation due to the finite size of mesons. Commutation relations and the rest frame Hamiltonian are obtained. In this frame, the relative energy of the quark and antiquark is shown to vanish.
