About ISUD

The biennial International Symposium on Ultrasonic Doppler Methods for Fluid Mechanics and Fluid Engineering (ISUD) is the most important scientific symposium on ultrasonic Doppler methods. Its purpose is to bring together both specialists and newcomers to share their knowledge about ultrasonic Doppler methods and to present the numerous studies using such methods. As well, we will discuss the development of related methodology and implied future prospects.


ISUD conference was first launched in 1996 at Paul Scherrer Institute in Switzerland by Professor Yasushi Takeda, who was already using and developing an ultrasonic Doppler method and apparatus for physics applications since the eighties. Seeing the extraordinary potential of all related methods and the growing interest of researchers worldwide in various scientific fields, he decided to establish a regular meeting where anyone of concern could exchange experiences, results and methodology issues. Since then the success of this international symposium has never stopped growing, leading to its original triennial frequency being reduced to two years as of the third edition in 2002 due to an increasing number of presentations.


The purpose of the Symposium is to convene both specialists and newcomers to share the present knowledge about the ultrasonic Doppler methods, presenting the various studies conducted using such methods, the related methodology development itself and the implied future prospects.


Approximately one third of the studies presented deals with fundamental scientific topics while the remaining two third aims at engineering applications. Recent trends are spatio-temporal flow structure analysis, large-scaled measurement in environmental hydraulics, studies of industrial flows such as liquid metal or multi-phase oil flows, and integration of the method for in-line process-control monitoring rheological properties of flowing food suspensions. New connections were recently initiated with researchers in the medical field where ultrasonic Doppler methods were first used.
