Abstract: When inserted in the gas side of a hydraulic accumulator, elastomeric foams can reduce the thermal loss and significantly improve the efficiency of this device. In this study, an open-cell ...

Abstract: A thermal time-constant correlation based on experimental data is presented for gas-charged hydraulic accumulators. This correlation, along with the thermal timeconstant model, permits accurate ...

Abstract: A hydraulic accumulator is often modeled as a gas spring following a polytropic process, but this fails to properly account for the dissipative effects of heat transfer which produce damping ...

Abstract: An algorithm for computing nonflow gas processes is based on the Benedict-Webb-Rubin equation of state and a thermal time constant to describe heat transport. Specific results are presented for ...

Abstract: Hydraulic regeneration systems have been considered by the automotive industry for implementation in hybrid vehicles for a number of years. The combination of an internal combustion engine and ...

Abstract: This study reports experimental data taken with a hydraulic energy regeneration system and compares the measured data with analytical results. The system tested consisted of two foam-filled ...
