This clearly shows that a high-speed liquid-jet ejection velocity can be estimated using the presented FDM when considering the variation in liquid density but neglecting the liquid viscosity. Our results indicate that the liquid-jet ejection velocity estimated by the FDM corresponds to that predicted by ANSYS/FLUENT for several different ignition-powder weights. Using the FDM, we consider the liquid density variation but neglect the effects of the liquid viscosity on the liquid ejection. In addition, we propose a fluid dynamic model (FDM) for estimating the high-speed liquid-jet ejection velocity based on the piston velocity. To reproduce the piston motion during the numerical simulation, the boundary-fitted coordinates and a moving boundary method are employed. To gather the input data applied during the numerical simulation, the piston motion is captured with a high-speed CMOS camera, and the velocity of the piston is measured using motion tracking software.

We apply a two-dimensional numerical simulation with an axisymmetric approximation using the commercial software ANSYS/FLUENT. Herein, we investigate the liquid ejection mechanism and a technique for estimating the ejection velocity of a high-speed liquid jet using a pyro jet injector (PJI). The test data can also help engineers refine their understanding of the engine component design.The high-speed liquid-jet velocity achieved using an injector strongly depends on the piston motion, physical property of the liquid, and container shape of the injector. Test Devices is developing equipment and methodologies to help evaluate the performance of components in an environment beyond 1400F for heated test applications The data from Test Devices tests help engineers and scientists to understand and validate the durability and integrity of critical engine components.
