Abstract:
The transport of powder materials is an important aspect of process engineering. Various industries such as
the food, chemical, pharmaceutical, coating, information and telecommunication industries have set a high
demand on the performances of existing plants, which are mainly for bulk powder transfer. Modern systems
demand powder transport systems which have a high quantitative accuracy. Therefore, the ultrasonic
material transport process technology has in the last few years developed into an attractive alternative
compared to the classical technologies. This technology involves transfer of powder through a pipe in
which the ultrasonic waves are transmitted. However, this technology is not refined. In this paper, the
optimal placement of the piezoelectric transducer on the pipe in order to produce traveling ultrasonic waves
is investigated. A given length of the pipe is considered for transmission of the ultrasonic waves.
