Introduction: As the basic physical properties of fluid, specific heat capacity is an important physical quantity for evaluating fluid materials, especially functional fluid materials, in scientific research projects and industrial production processes. It is also one of the important parameters in the calculation process of thermal processes, thermal design processes, and thermal systems. Measurement methods Specific heat measurement methods, including differential thermal analysis (DTA), differential scanning calorimetry (DSC), adiabatic heating, electric pulse heating, flow type, etc., in which the flow specific heat test method is specialized The method for measuring the specific heat of a fluid is mainly that the sample is heated and temperature-measured when flowing in a stable manner in the pipeline, and the heat insulation is achieved through a high-vacuum system, the accuracy is less than 1%, and the applied temperature range reaches 700 K, and the pressure reaches 40MPa, is the most direct and reliable experimental method for obtaining fluid specific heat data. The measurement principle of the flow calorimetry is as follows: The sample flows steadily in the pipeline and the specific heat is measured by measuring the temperature rise produced by the fluid passing through the core heating zone, thereby realizing the measurement of specific heat. Adiabatic insulation is achieved by a high vacuum system with a measurement accuracy of less than 1%. At present, the application temperature of the flow calorimeter is up to 700K and the pressure is up to 15MPa.
