Comparative Study of the Effect of Fuel Deoxygenation and Polar Species Removal on Jet Fuel Surface Deposition

“…The nonlinear temperature rise along the external surface of a simulated burner feed arm under engine representative condition is reported in refs. 40,39 By virtue of mounting a pyrometer on an automated positioning bed, the temperature in the localized areas can be captured as discrete measurement points, along a small section of the capillary, and used to create a time-profile of temperature rise along the wall. The main advantage of the HiReTS method is the ability to quantify the thermal stability of fuel using relative measures such as HiReTS number.…”

“…Our previous findings show that the profile of temperature rise along a heated tube in an aeroengine representative condition is nonlinear and fuel-specific. The nonlinear temperature rise along the external surface of a simulated burner feed arm under engine representative condition is reported in refs. , …”

Effects of geometric parameters of rectangular cooling channel on pyrolysis carbon deposition in fuel‐cooled plates

“…In numerical simulation of thermal oxidation coking of hydrocarbon fuel, these wall reactions and bulk reactions are usually solved synchronically. [31,32] That is, the components generated/consumed in the wall reactions can be also taken as the source term of the species conservation equation in the bulk reactions. This can be called the coupling algorithm, through which the carbon deposition rates at all positions of the fluid-solid interface can be obtained with efficient and steady-state numerical simulation.…”

Synthesis and Performance of a Series of Polyisobutylene-Substituted Succinic Acid Ester Dispersants for Reducing Thermal Oxidation Deposition of Jet Fuel

“…In advanced aircraft, the aviation fuel is not only used as a power source but also as a primary coolant in the onboard thermal management system to remove excessive heat load. − During the heat exchange process, the temperature of the jet fuel increases and when it reaches about 150 °C, the hydrocarbons in the fuel will begin to react with dissolved oxygen to produce thermal oxidation deposition. , This will cause severe problems to the aeroengine, for example, it will block the tubes, nozzles, and valves, affect the heat exchange system, and may eventually even cause flight accident. − …”
