Summary of the 4th IAHR Asian working group symposium on hydraulic machinery and systems

Abstract 1. Background The international Association for Hydro-Environment Engineering and Research (IAHR), founded in 1935, one of the IAHR Committee is the Hydraulic Machinery and Systems, which deals with the advancement of technology associated with the understanding of steady and unsteady flow characteristics in hydraulic machinery and conduit systems connected to, and the main emphasis is to promote interaction between the machine designers, machine users, the academic communities, and the communities at large. To meet its objectives, the Committee focuses on the best possible exchange of technical knowledge by arranging a Committee Symposium every second year. The symposiums are designed to attract scientists and engineers from industries, universities, consultants and users of hydraulic machinery. In addition, the Committee established “Asian Working Group” specially to promote the exchange and cooperation of hydraulic machinery industry in Asian countries. In recent years, water conservancy and hydropower in Asia have been developing dramatically. Hydraulic machinery like pump, pump turbines etc., are widely used in project construction. There are plentiful scientific and technical payoffs achieved within the related researches. The "Asian Working Group" has held three symposiums on hydraulic machinery and systems, which are: IAHR 2017 Asia Beijing, IAHR 2019 Asia Busan, IAHR 2021 Asia Nepal. And all conference proceedings have been published in IOP. After the 4th IAHR Asian Working Group Symposium on Hydraulic Machinery and Systems (hereinafter referred to as IAHR 2023 Asia Kashgar) following its convention, the conference proceedings will be published in IOP.
