The HiReTS was developed by Shell Global Solutions, Fuels Business Group as a small- scale unit for evaluating the thermal stability of jet fuel prior to shipment to the consumer. The HiReTS was designed to operate at high fuel flow rates through a heated, stainless steel tube capillary representative of turbulent flow conditions in actual engine fuel injectors. At the standard operating conditions SOC, the HiReTS has a Reynolds Number Re of approximately 13,000, well within the turbulent regime. The presence of high turbulence in the HiReTS also eliminates the sensitivity of mass transport effects that occur in laminar flow test devices such as the Jet Fuel Thermal Oxidation Tester JFTOT, which operates at a Re of approximately 10.
