Methane Cluster Fragmentation by Fast Electron Impact

open access: yesAtoms, 2023
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 Hugoniot Analysis for Steady Combustion Waves in Propulsion Systems [PDF]

open access: yes, 2006
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 ...

Development of an Analytical Method for Predicting Flow in a Supersonic Air Ejector

open access: yesEPJ Web of Conferences, 2016
The article deals with development of an analytical method for predicting flow in an ejector with twelve supersonic nozzles, which are located at the periphery of the mixing chamber of the ejector.

Stagnation pressure probe [PDF]

open access: yes, 1974
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

A proposed correlation for critical flow rate of water flow

open access: yesNuclear Engineering and Technology, 2015
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).

Plasma-Assisted Control of Supersonic Flow over a Compression Ramp

open access: yesAerospace, 2019
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.

Numerical Study on Aerodynamic Characteristics of Heavy-Duty Vehicles Platooning for Energy Savings and CO2 Reduction

open access: yesEnergies, 2022
This study aims to analyze the aerodynamic interaction between moving vehicles platooning with the change in the platooning conditions on a freeway. The effect of the vortex generated by the forward vehicle reduces the value of the stagnation pressure ...

IN THE SHOWERHEAD REGION OF A GAS TURBINE VANE PART I: STAGNATION REGION AND NEAR-PRESSURE SIDE

open access: yes, 2015
An experimental program to study film cooling adiabatic effectiveness in the showerhead region of a turbine vane was completed. A typical first stage turbine stator vane was modeled in a nine-times scale, low speed test facility.
