This paper introduces a data transmission and processing system for the speed governor test-bed. And the design employed the Internet of things (IOT) technology, added the WIFI communication module on the traditional speed governor test-bed, as well as combined the database and WEB server, which enabled the data measured by the speed governor test-bed to be stored in the database in real-time. In addition, the experimenter can remotely retrieve and view historical experimental data and view the direct results of data processing. It solved the issue that the data and information in the process of governor testing can be transferred and transmitted efficiently and reliably among all levels and layers, and accordingly enhanced the ability of data storage and fast retrieval in the process of governor testing.

Numerical simulations and experiments are carried out in this paper to research about characteristics of heat transfer, frictional resistance and comprehensive performance of turbulent water flow (3000
