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 pump supplies energy to the system to actuate a double-acting cylinder periodically. The pressure losses within directional valve converts the energy into heat. Heat transfer through the cylinder casing to the environment provides a heat sink.
