Stanadyne LLC is a global leader in fuel systems technology. Much of their current research and development involves low and high-pressure gasoline and diesel fuel pumps and fuel injectors. Within the development process of these fuel pumps, Stanadyne utilizes hydrodynamic fuel simulations to analyze their designs. The quality of these simulations depends on the accuracy of the fuel properties assigned as engineering data in the simulations. Specifically, density, viscosity, and bulk modulus are critical properties of fuel in the design and development of fuel systems technology. Temperature and pressure both have considerable effects on these properties. This project aims to measure the density and bulk modulus of working fluids at a maximum pressure of 34 MPa and at a maximum temperature of 200 °C to validate the hydrodynamic simulations and equations of state fuel models. The test device computes density using volumetric and mass flow rate measurements. Bulk modulus is computed using the collected data of pressure vs. density. The team completed the fabrication and validation of the test mechanism and acquired measurements. ME52 collaborated with team ME54, as they measure the viscosity using the test mechanism at the same pressure and temperature. A system design capable of withstanding 100 MPa at the same temperature for further experimentation has also been recommended.
