摘要：In this paper, an experimental study on the hydrodynamic characteristics of cyclohexane has been conducted at pressures of 2.5-5.5 MPa, inlet temperature of 30-100 degrees C and heat flux of 60-205 kW/m(2). The hydrodynamic characteristics curves of the cyclohexane were obtained in a horizontal stainless steel tube with 2.0 mm hydraulic diameter. The multi-valued hydrodynamic characteristics were analyzed theoretically and experimentally. In experiments, the effects of the system pressure, inlet temperature and heat flux on the hydrodynamic characteristics were studied. And the dimensionless parameter boundaries of the negative slope area on the hydrodynamic characteristic curves were obtained for trans- and supercritical fluid. (C) 2017 Elsevier Ltd.
