Modelling for isothermal cavitation with a four-equation model

A Simple Model for Cavitation with Non-condensable Gases

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

A New Isothermal Equation of State for Solids

A new isothermal equation of state (EOS) for solids is derived by starting from the theory of lattice potential and using an analytical function for the volume dependence of the short-range force constant. A critical analysis of the isothermal EOSs: Murnaghan EOS, Vinet EOS, and the new EOS derived here, is presented by investigating the pressure-volume data for rare gas solids, metals and mine...

An Information Security Culture Model Validated with Structural Equation Modelling

Information security culture must be considered as part of the information security programme to direct employee behaviour. Such a culture can contribute to the protection of information and minimise the risk that employee behaviour poses. This paper proposes a theoretical model, i.e. an information security culture model (ISCM) with four mechanisms (i.e. management, policies, awareness and com...

A mixture-energy-consistent six-equation two-phase numerical model for fluids with interfaces, cavitation and evaporation waves

We model liquid-gas flows with cavitation by a variant of the six-equation single-velocity two-phase model with stiff mechanical relaxation of Saurel–Petitpas–Berry [J. Comput. Phys. 228 (2009), 1678–1712]. In our approach we employ phasic total energy equations instead of the phasic internal energy equations of the classical six-equation system. This alternative formulation allows us to easily...
