Breakthrough Research in Cavitation of Axial Flow Pumps
November 11, 2015

The leading publication in the multi-phase flow field, The International Journal of Multiphase Flow (2015) published a research paper written by Associate Prof. Zhang Desheng, the doctorial supervisor of Fluid Machinery Engineering and Technology.

This research has been supported by the National Natural Science Foundation. Related research achievements have been published in leading periodicals in China and abroad, more than 30 of which are indexed in SCI and EI. This research won first prize in the Scientific and Technological Advance Award of Chemical Industry by Sinopec. It also won two second prizes in Scientific and Technological Advancement Awards from The Ministry of Education.

By high speed photography experimental facility, this research identified the special vertical cavity vortex in the entrance of an axial-flow pump's plate. Prof. Joseph Kata and his research team at Johns Hopkins University in US, recently produced the same results. Both verify that the vertical cavity vortex in an axial-flow pump is a common physical phenomenon. Prof. Zhang first identified the formation mechanism and unusual cavitation evolution process of a vertical cavity vortex through mathematical simulation, a key finding in the research.

Cavitation is a complex phenomenon in the field of hydraulic machinery. The Cavitation process involves phase change, morphological evolution and other complex physical processes. In recent years, under the lead of researcher Shi Weidong, his research team in Fluid Machinery Engineering and Technology have carried out in-depth research in the field of axial (diagonal) flow, pumps and cavitation. More than 10 related papers have been published in the world top journals, such as The International Journal of Multiphase Flow, ASME Journal of Fluid Engineering, Computers & Fluids, The International Journal of Numerical Methods for Heat & Fluid Flow. These achievements intensify the academic influence of Jiangsu University in fluid machinery and engineering all over the world.
