Multi-faceted visualization flow heating experimental device

Abstract

The invention provides a multidimensional visualization flow heating experimental device. The device includes an observation section, and an inlet joint and an outlet joint which are connected with both ends of the observation section through a flange. The inlet joint and the outlet joint are respectively connected with an external experimental loop; the cross section of the observation section is square; the observation section comprises an observation section body, ITO heating glass arranged on four faces of the observation section, and an observation window installed outside the ITO heating glass; and the observation section body is provided with a wire hole connected to the external circuit. The invention can simulate flow heating in industrial equipment to conduct visualization research on flow and heat transfer characteristic of a fluid working medium, and has the advantages of simple and compact structure, convenience for visual observation, and wide range for research on condition.

Description

technical field [0001] The invention relates to a flow heating experiment device, in particular to a multi-faceted visualized flow heating experiment device. Background technique [0002] The development of modern industry is inseparable from the demand for energy. Under the premise of a certain total energy reserve, the efficiency of energy utilization is very important. The cognition of the flow and heat transfer laws of fluid working fluid is helpful to improve the energy utilization process and improve the utilization efficiency, so many scholars at home and abroad have made a lot of research on this. In traditional experimental research, metal heaters are generally used for heating, and thermocouples and flowmeters are used to measure temperature and flow for further analysis. This type of traditional experiment has certain limitations. For example, when measuring the flow velocity through a flowmeter, only the overall average velocity can be obtained, and the local fl...

Sun Licheng also conducted a visual observation experiment in "Research on Flow Boiling Heat Transfer in Vertical Annular Flow Channel" (Journal of Harbin Engineering University. Volume 32, Issue 5, May 2011). The author adopts the heating method of reverse flow heating of cold and hot water; although this heating method can realize all-round visual observation, the heat flux of the heating is not uniform, and the experimental conditions of constant heat flux cannot be studied
