Hydraulic Fluid Warming due to Losses

This example model shows how Foundation Library thermal liquid components can be used to estimate the impact of viscous losses on an actuating system's temperature over a long time scale. A double-acting cylinder is actuated periodically and the pressure losses within the custom directional valve add heat to the flow. The conductive heat transfer through the cylinder casing provides a heat sink. The competition between the source and the sink results in a steady temperature established after about 10 minutes. The pressure relief valve limits the pressure inside the system.
