Isentropic Bulk Modulus: Development of a Federal Test Method

Abstract

The overall objective of this effort was to construct additional bulk modulus units based on the previous prototype built at Southwest Research Institute (SwRI). The current methodology allows the measurement of isentropic bulk modulus via speed-of-sound and density at temperatures ranging from 30-80 C and applied pressures of 1,000-18,000 psi. This method has been applied successfully to aviation turbine fuels and diesel fuels composed of petroleum, synthetic, and alternative feedstocks and is currently a requirement in fit-for-purpose (FFP) testing toward qualification of aviation fuels and additives. A round robin test program was carried out on selected fuels and precision data calculated. A Federal Test Method (FTM) was drafted based on the current methodology and supporting round robin data. The results from this effort have demonstrated that these units have the ability to provide accurate and repeatable data across a range of temperatures and pressures.
