A METHOD AND APPARATUS FOR TESTING THE THERMAL STABILITY OF AN (AVIATION) FUEL

摘要

A method and apparatus for testing the thermal stability of an (aviation)fuel. Under pressure a fuel sample to be tested is suppliedto a small-bore capillary tube (2) of a test section and the fuel in the testsection is allowed to be heat stressed. The fuel sample in the testsection is under turbulent flow regime. The thermal degradation of the testfuel within the section is monitored by measuring by means ofcontactless thermometry the outer wall temperatures along the test section andsubsequent increases in these temperatures, promoted by theinsulation effect of fuel degradation products. From the temperature data,thus obtained, information on the thermal stability of the fuel isderived.
