DURIP Novel Measurements in Multiphase and/or Turbulent Supersonic and Hypersonic Flows
Abstract
Publicly Releasable Project Summary/AbstractProject Title: Novel Measurements in Multiphase and/or Turbulent Supersonic and HypersonicFlowsProgram Manager: Eric Marineau, Code 351, Hypersonic Aerothermodynamics, High-SpeedPropulsion and MaterialsThe overall objective of this equipment request is to enable high-quality measurements in turbulentand/or multiphase supersonic and hypersonic flows for the purpose of fundamental physicalunderstanding and code validation. If this equipment request is successful, we will be able to executeand instrument tests at Stevens at a sufficiently high Reynolds number to investigate turbulentboundary layers at Mach 3.5,5.2, and 6 at cold and enthalpy match conditions; also at Mach 8 atcold conditions. We are requesting support for:1. Dedicated Mach3.5 nozzle manufactured by Tri Models. Cost $124,899.26Impact: We are requesting a Mach 3.5 nozzle because of the need for high-Reynolds numberturbulence measurements for #Turbulence Quantities in Supersonicand Hypersonic Flows(N00014-23-1-2474).#2. Nozzle/test-section mating flange and supporting hardware.Impact: We are requesting a new flange where the nozzle slots into the slip-seal of thetestsection.3. Mach 5.25 throat for the Stevens Shock Tunnel.Impact: We are requesting a new throat for our Mach 6 nozzle which will reduce the arearatio and Mach number but increase the Reynolds number. (The Mach 6 nozzle cannot bemodified to produce Mach 3.5 flow by design restrictions at the throat and concerns on slugsize. The Mach 8 throat is being supported by internal Stevens money.)4.Heating system for the Stevens Shock Tunnel.Impact: We are requesting a system to heat select portions of the Stevens Shock Tunnel toexpand the operational envelope of the facility. Heating the driver section and using heliumwill enable Stevens to test at Mach 8 equivalent enthalpy. We are also proposing to heatthe driven section and eliminate the driver and operate the facility as a Ludwieg tube for theMach 3.5 cases.5. Pressure transducers and thermocouples for the operation of the Stevens Shock Tunnel withheated tubes.Impact: We are requesting four high-temperature pressure transducers and four high-temperaturethermocouples to monitor the tube pressures and temperatures with the heaters.6. New seed laser for optical-parametric-oscillator (OPO).Impact: We are requesting a new 920-985 nm seed laser for our OPO. This new seed laserwill enable us to reach the 216.6 nm line for krypton tagging velocimetry (KTV) and enableus to explore new ideas for advanced laser diagnostics.7. New BBO crystals for OPO operation.Impact: We are requesting newBBO crystals to maintain the optimal performance of theOPO for the highest-possible quality measurements for this grant.8. Silux laser for high-speed schlieren/shadowgraph.Impact: We are requesting a Silux laser for high-speed schlieren/shadowgraph to be used forN00014-20-1-2682 (Precipitation) and N00014-23-1-2474 (Turbulence Quantities).
