Abstract

A mathematical model of a thermo-hydraulic system has been developed based on the analysis of heat transfer in a hydraulic circuit containing a piston hydraulic cylinder, a hydraulic pump, and a hydraulic directional control valve. For a more accurate thermodynamic analysis of the hydraulic system, a new methodology is proposed based on solving a coupled problem, namely, the problem of constructing a complete thermo-hydraulic system model. The simulation results showed good agreement with the calculated data.
