Abstract

The thermal hydraulic investigation of hydraulic channels is presented. Changes of pressure and flow values due to non-steady thermodynamic processes were considered. Main aim of investigation is to ensure hydraulic calculation, that had been made to predict working characteristics of hydraulic drives at design stage, for the variable temperature environment. Structural analyses of the flow circumstances along channels were made with taking in to account temperature gradient and viscosity changes. Numerical simulation had been made to find out period of velocity stabilization and its value. The investigation considers geometry and shape of channels via taking in to account pressure reduction and velocity changes in hydraulic system. Results of investigation allow to increase the precision of hydraulic calculation for drive, that works at variable temperature and none-stable modes, using proposed method.
