Implementation of Bubble Dynamic Effects by Coupling the Gilmore Equation With Fluid Dynamic Equations Using the Method of Characteristics

Fabian Guse, Enrico Pasquini, Katharina Schmitz
Proc. ASME. FPMC2020, BATH/ASME 2020 Symposium on Fluid Power and Motion Control, V001T01A020, September 9–11, 2020
Paper No: FPMC2020-2745
DOI: https://doi.org/10.1115/FPMC2020-2745
...Abstract Abstract In fluid power systems, performance as well as system dynamics are strongly influenced by the presence of bubbles — especially for low system pressures. While the static effect of dissolved air (especially the volume fraction of dissolved air) on the bulk modulus has been...
