Numerical Modeling and Analysis of the Pressure Pulse Generated by Drop Mass Calibration Device

This study focuses on the development of a computational fluid dynamics (CFD) model using Ansys Fluent to predict maximum pressure and pressure changes over time.The accuracy of hydraulic modeling is directly influenced by the bulk modulus of hydraulic oil, making it a crucial characteristic to study.Experimental data was used to validate the results obtained from the CFD model.Furthermore, an in-depth investigation was conducted to analyze the fluid bulk modulus and its correlation with the presence of air trapped inside the cylinder.The findings of this research provide valuable insights into the behavior of hydraulic systems and the importance of accurate fluid property characterization for effective modeling.
