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 hydro turbine, pump, and 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 four symposiums on hydraulic machinery and systems, which are: IAHR-Asia 2017 in Beijing, IAHR-Asia 2019 in Busan, IAHR-Asia 2021 in Kathmandu and IAHR-Asia 2023 in Kashgar.
