Stagnation Hugoniot Analysis for Steady Combustion Waves in Propulsion Systems [PDF]
The combustion mode in a steady-flow propulsion system has a strong influence on the overall efficiency of the system. To evaluate the relative merits of different modes, we propose that it is most appropriate to keep the upstream stagnation state fixed ...

Stagnation pressure probe [PDF]
A method and apparatus for measuring the stagnation pressure of supersonic velocity gas streams without the generation of shock waves which interfere with such measurements are given. The technique is insensitive to the type of gas and Mach number and is

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 ...

A proposed correlation for critical flow rate of water flow
A new correlation predicting the idealized critical mass-flow rates of water for subcooled and saturated liquid water including two-phase water flow was developed for a wide range of upstream stagnation pressures (e.g., 0.5–20.0 MPa).

Methane Cluster Fragmentation by Fast Electron Impact
We investigate the fragmentation of the CH4 cluster by fast electron impact at stagnation pressures from 0.5 bar to 16 bar. By measuring the time of flight spectrum (TOF), two types of ions, including (CH4)n−1CH5+ and (CH4)n−2(C2Hm)+, are observed.

Stagnation–saddle points and flow patterns in Stokes flow between contra-rotating cylinders [PDF]
The steady flow is considered of a Newtonian fluid, of viscosity mu, between contra-rotating cylinders with peripheral speeds U-1 and U-2 The two-dimensional velocity field is determined correct to O(H-0/2R)(1/2), where 2H(0) is the minimum separation of

Plasma-Assisted Control of Supersonic Flow over a Compression Ramp
This study considers the effect of an electric discharge on the flow structure near a 19.4° compression ramp in Mach-2 supersonic flow. The experiments were conducted in the supersonic wind tunnel SBR-50 at the University of Notre Dame.
