Suitability of a radical based method for assessment of jet fuel antioxidant capacity and projected storage stability

Novel Experimental Approach to Studying the Thermal Stability and Coking Propensity of Jet Fuel

“…Several other experimental rigs with single-tube heat-exchanger configurations have been reported in the literature, for example, the Shell Development Company Heat Transfer Test Rig, the NASA Glenn Research Center Heated Tube Facility, the Phoenix rig of the U.S. Air Force (USAF), − the near-isothermal flowing test rig (NIFTR), − the Australian Defence Science and Technology Organisation (DSTO) Thermal Stability Rig, , the flow reactor of the Pennsylvania State University (PSU) Energy Institute, , various designs from United Technology Research Center (UTRC), ,, and the single-tube heat-exchanger apparatus of the University of Toronto Institute for Aerospace Studies (UTIAS). ,, The test sections of these test rigs employ different methods for heating. For example, the Phoenix, NIFTR, and UTRC rigs embed the test section into a copper block and conductively heat it with an external electrical heater to achieve isothermal heating. ,,− Test sections are also heated directly by flowing electrical current through them to achieve pyrolytic temperatures and constant heat flux in the Shell Heat Transfer Test Rig and others. − A fluidized sand bath is used to heat the submerged test section in the DSTO rig, , whereas the PSU and UTIAS rigs use radiative heating of the test section by electrical tube furnaces. ,, …”
