Abstract

The invention discloses a rotating platform condensation heat transfer experimental device and a rotating platform condensation heat transfer experimental method. According to the method, an operating state of a drying cylinder can be accurately simulated. Various thermal parameters of a channel are transmitted to a computer in a wireless transmission mode, and the rotating speed of a rotating disc can be adjusted, so that the drying cylinders with different speeds can be simulated. The device consists of a constant temperature chamber, a vertical rotating platform and a condensation heat transfer experimental section applied to the platform, wherein the condensation heat transfer experimental section is divided into two parts, namely a steam section and a cooling agent section. According to the device and the method, a steam condensation phenomenon in the cylinder in the process of operating the drying cylinder can be accurately simulated.

Description

technical field [0001] The invention belongs to the technical field of two-phase flow experimental measurement, and relates to a vertical rotating platform, a steam generation and condensation method, a method for photographing the steam condensation process and automatically adjusting experimental parameters, in particular to a rotating platform condensation heat exchange experimental device and method. Background technique [0002] my country is the world's largest paper producer, and the paper industry is an important pillar industry of my country's national economy. As the most important equipment in papermaking equipment, the paper machine's research and development play a decisive role in revitalizing my country's papermaking equipment manufacturing industry.
