Abstract

Gas-charged accumulators serve as fundamental components in various technical systems, functioning both as primary units and supplementary safety devices. These systems may incorporate conventional pneumatic actuators or specialized actuator designs that form integrated mobile assemblies with the accumulator tank. This study develops and analyzes a thermodynamic model of gas behavior within accumulator tanks, with particular emphasis on heat exchange effects between the internal gas and external environment. A dimensionless criterion is derived from ideal gas thermodynamics to structurally and qualitatively evaluate these thermal interactions. The criterion enables rapid comparative analysis of system properties between real and ideal gas models. Certain applications may warrant development of analogous criteria for real gas models. The analysis employs technical measurement units to facilitate conversion to dimensionless parameters and process description. The proposed modeling approach provides a framework for evaluating thermal effects in gas-charged accumulator systems, with potential applications in design optimization and performance assessment
