AIAA 99-0772 Measurement of NO Density in a Free- Piston Shock Tunnel using PLIF
We investigate the feasibility of using a combined absorption – planar laser-induced fluorescence (PLIF) method for measuring nitric oxide (NO) number density in the freestream of a free-piston shock tunnel. The absorption coefficient is determined from the exponential decay in PLIF intensity through a uniform region of flow. The NO density is determined from the measured absorption coefficient...
متن کاملAIAA 98–2703 PLIF Thermometry of a Free-Piston Shock-Tunnel Nozzle Flow
Planar Laser-Induced Fluorescence PLIF is employed to measure rotational temperatures at the nozzle exit of a free-piston shock tunnel. The ow is at approximately Mach 7 and chemical eeects have been reduced by using a nitrogen test gas and low total enthalpy 5 MJJkg. Vibrational freezing in the nozzle expansion has an appreciable effect on the nozzle-exit rotational temperature, and therefore ...
متن کاملA Shock Tube Driven Transonic Wind Tunnel
A small transonic wind tunnel was designed, constructed and calibrated in order to provide a tool for the study and demonstration of transonic flow phenomena. The wind tunnel makes use of flow properties following the propagation of a shock wave along a tube in order to create the transonic flow. This is in contrast to conventional transonic facilities which are supplied from a reservoir or com...
متن کاملComputational fluid dynamical modelling of supersonic combustion and comparisons with experiments in a free piston shock tunnel
Computational fluid dynamical simulations were carried out for a number of different scramjet configurations, which differed in their values for the location and angle of the thrust surface. These configurations were investigated experimentally in free-piston shock tunnel tests. The comparison between simulations and experiments indicated that the code successfully predicted the pressure levels...
متن کاملBubble Wake Interaction with Convective flow from a heated vertical flat plate
Time-synchronised flow velocity, temperature, and heat flux measurements were preformed to characterise the interaction of a single rising ellipsoidal bubble with the free convection flow from a heated vertical flat surface. The heat transfer measurements from the surface were provided by a hot film heat flux sensor calibrated using a pre-calibrated microfoil heat flux sensor. Two thermocouples...
