“…Recently, QC has been identified as a very promising high-energy compound as replacement for, or additive to, current hydrocarbon-based rocket propellants, because the extraordinary high strain energy offers a very high specific impulse (Kokan et al, 2009;Striebich & Lawrence, 2003). It is reported that QC-based fuels provide more propulsion than most of the hydrocarbon fuels like rocket propellant RP-1.…”

“…All of these have their pros and cons for varying levels of simulation fidelity, complexity, control, and quantitative determination of results. The bulk of the data generated has been from heated tubes and the conduction heated thermal concentrator [1][2][3][4][5][6][7][8][9][10][11][12] . Direct ohmic heating of both pure metal and bimetallic coannular tubes produces high wall temperatures and circumferential heat transfer to the fuel coolant.…”

“…Direct ohmic heating of both pure metal and bimetallic coannular tubes produces high wall temperatures and circumferential heat transfer to the fuel coolant. External wall temperature measurements and electrical power consumption are used to infer the internal wall temperature [2][3][4][5][6][7][8]11,12 . The implementation is relatively simple and allows for easy interrogation of posttested specimens for coking and corrosion behavior.…”

With both the Air Force and NASA interested in developing reusable hydrocarbon-fueled engine technologies for reusable launch vehicles, there is an increased need to better understand the thermal stability of hydrocarbon fuels under high heat fluxes encountered during regenerative cooling. Currently, no existing thermal stability test rig can accurately simulate the high heat flux conditions that will exist in the cooling channels of these new high-pressure hydrocarbon engines. To meet the high reliability and reusability requirements proposed for these engines, the Air Force Research Laboratory (AFRL) has designed a High Heat Flux Facility (HHFF) using experience gained from past and present thermal stability test rigs. CFD++, a Metacomp Technologies Inc. computational fluid dynamics software suite, was employed to optimize the design prior to manufacture. Conjugate heat transfer calculations were performed in a single computational domain containing the copper heater block and the fluid channel of the new test rig design. The first tests conducted in the facility will be highly instrumented and will be used to validate the CFD++ calculations. The parameters of interest for a given geometry are the heat transfer coefficient, the degree of coking and corrosion in the channel, and the pressure drop as functions of heat flux, wall temperature, Reynolds number, channel material, fuel composition and pressure. The HHFF will be an important tool to facilitate the development and transition of new advanced hydrocarbon fuels under study by AFRL.

“…Wall temperatures, from 500-1100 °F for copper walls, can vary from mild to pushing the safety factor for the structural integrity of the wall material and heat flux rates vary from 1 to 100 BTU/in 2 /sec, producing a range of boundary layer thicknesses and potential striations. Facilities used for studying heat transfer behavior and fuel thermal stability in the United States are resistively heated tube facilities (such as NASA Glenn Research Center's Heated Tube Facility Rig, and UTRC 5,6 and Rocketdyne's 7,8 heated tube rigs), conductively heated thermal concentrators (such as Aerojet's Carbothermal rig 9,10 ), combustion, arc lamp and laser heating facilities, with the bulk of the data generated coming from the heated tube and conductively heated concentrators [1][2][3][4][5][6][7][8][9][10][11][12] . For the heated tube facilities, direct ohmic heating of both pure metal and bimetallic co-annular tubes is used to produce high wall temperatures and circumferential heat transfer to the fuel coolant.…”

The Air Force Research Laboratory's Propulsion Directorate is developing higher energy density hydrocarbon fuels for application in reusable liquid rocket engines. For increased performance and operability, next generation engines will require better thermal stability understanding of hydrocarbon fuels under high heat fluxes. Of the existing thermal stability test rigs, none have the ability to accurately simulate the high heat flux conditions that will exist in the cooling channels of these new high-pressure hydrocarbon engines. To design and test fuels to meet the high reliability and reusability requirements proposed for these engines, the Air Force Research Laboratory (AFRL) at Edwards AFB has designed the High Heat Flux Facility (HHFF) using experience gained from past thermal stability test rig experiments. In order to design a facility capable of simulating the higher heat fluxes expected in the channels, CFD++, a Metacomp Technologies Inc. computational fluid dynamics software suite, was employed to optimize the design prior to manufacture. Conjugate heat transfer calculations were performed in a single computational domain containing the copper heater block and the fluid channel of the new test rig design. The parameters of interest during each experiment will be heat transfer coefficient, degree of coking and corrosion in the channel, and pressure drop as a function of heat flux, wall temperature, Reynolds number, channel material, fuel composition and pressure. AFRL's HHFF will be an important tool for facilitating the development and transition of new advanced hydrocarbon fuels.
