In engineering practice, when the flight Mach number is beyond the design Mach number, or the actual flight attack exceeds rated value, the waves generated by forebody would interact with lip boundary layer, which may result in inlet unstart. In figure 1, a sizable wave pattern occurs at the lip leading edge, which includes various basic physical appearances such as viscous flow, separation, an...

Abstract In order to study the effect of MHD control on separation flow turbulent boundary layer in scramjet inlet based assumption low magnetic Reynolds number, considering source term electromagnetic dissipation, numerical simulation method is developed for field coupled with field. A Mach 4 plate adopted as basic configuration assess accuracy solver’s dissipation. On this basis, carried out ...

This memo specifies enhancements to the General Switch Management Protocol (GSMP) [RFC1987]. The major enhancement is the addition of Quality of Service (QoS) messages. Other improvements have been made to the protocol resulting from operational experience. GSMP is a general purpose protocol to control an ATM switch. It allows a controller to establish and release connections across the switch;...

A visible synchrotron light diagnostic beam line has been designed at the NSLS2 storage ring, using the dipole radiation. The ‘cold-finger’ configuration has been selected to block the central x-rays. Beam power on the first mirror is less than 1W, no water cooling is required for the in-vacuum mirror. The beam line layout and major applications will be discussed in this paper. Two vacuum ports...

The port industry is facing a dramatic wave of changes that have transformed the structure of the industry. Modern seaports are increasingly shifting from a “hardware-based” approach towards “knowhow intensive” configuration. In this context knowledge resources, learning processes and training initiatives increasingly represent key elements to guarantee the quality of service supplied and hence...

Unsteady three-dimensional flow in the mold region of the liquid pool during continuous casting of steel slabs has been computed using realistic geometries starting from the submerged inlet nozzle. Three largeeddy simulations (LES) have been validated with measurements and used to compare results between full-pool and symmetric half-pool domains and between a full-scale water model and actual b...

PURPOSE The purpose of this study is to explore the influence of segmentation of the upstream and downstream parent artery and hemodynamic boundary conditions (BCs) on the evaluated hemodynamic factors for the computational fluid dynamics (CFD) analysis of intracranial aneurysms. MATERIALS AND METHODS Three dimensional patient-specific aneurysm models were analyzed by applying various combina...

Power quality and neutral section are two technical problems that hinder the development of electrified railway to high-speed heavy railway. The co-phase power supply technology is one best ways solve these problems. At present, a V type connection traction transformer widely used in frequency single-phase AC system, especially In this paper, new system for based on proposed. One winding as mai...

During the continuous casting of steel, transient flow events can be very important to the generation of quality problems. These transient phenomena can be computationally modeled using Large Eddy Simulation (LES) models while conventional K-ε models yield time-averaged results. Recently, Particle Image Velocimetry (PIV) has been applied to measure quantitatively the transient velocity fields i...
