Moving Model Test of High-Speed Train Aerodynamic Drag Based on Stagnation Pressure Measurements. [PDF]
A moving model test method based on stagnation pressure measurements is proposed to measure the train aerodynamic drag coefficient. Because the front tip of a high-speed train has a high pressure area and because a stagnation point occurs in the center ...

Measurements of the stagnation pressure in the center of a cavitating jet [PDF]
The stagnation pressure at a certain distance from the nozzle is important for the erosion/ cutting capacity of a submerged jet in dredging. The decay of the stagnation pressure with jet distance is well known in the case of non-cavitating jets.

Definition of vortex boundary using stagnation pressure [PDF]
A novel method is proposed to identify vortex boundary and center of rotation based on tubular surfaces of constant stagnation pressure and minimum of the stagnation pressure gradient.

Increase in stagnation pressure and enthalpy in shock tunnels [PDF]
A new technique based on the insertion of a converging section in the driven tube is described which is capable of producing substantial increases in both reservoir pressure and enthalpy. A 1D inviscid full kinetics code is used to study a number of different locations and shapes for the converging driven tube section.

Empirical equation of the Mach number as a function of the stagnation pressure ratio for a quasi-one-dimensional compressible flow [PDF]
In the present work for a quasi-one-dimensional isentropic compressible flow model, an empirical equation of the Mach number is constructed as a function of the stagnation pressure ratio for an analytical equation that algebraic procedures cannot invert.

Interaction of two vortices in a flued with lower stagnation pressure [PDF]
The flow field induced by two point vortices of strength Γ \Gamma at a distance 2 h 2h apart in a quiescent field with lower stagnation pressure is investigated. The flow field around the vortices is bounded by a free streamline with constant velocity U U determined by the ...

Inertial confinement fusion requires the inertia of the imploding mass to provide the necessary confinement such that the core reaches adequate high density, temperature, and pressure. Experiments utilize low-Z capsules filled with hydrogenic fuel, which
