Simulations of the Freezing of Jet Fuel

Abstract

The objective of this research is to obtain images of the freezing of hydrocarbon fuels within a simple flow to assist understanding of the interaction between the flow and phase change dynamics. Another objective is to describe a computational model of the freezing process. JPTS, Jet A, and additized Jet A samples were cooled in a rectangular, aluminum chamber with quartz viewing windows. Images and surface temperatures were recorded during the solidification process. The images tracked the advancing freezing front and the influence of the buoyancy-driven flow. Cooling of JPTS resulted in the lowest volume of solids. When cooled, Jet A fuel containing a low-temperature additive exhibited a smaller solid volume than did the neat fuel. In addition, the additized Jet A fuel developed a population of suspended particles that was greater than that of neat Jet A fuel.
