Ultrasonic Research Papers

Our in-house development team carry out a wide range of research and testing in ultrasonics and its processes, to ensure that Ultrawave are at the cutting edge of the ultrasonic cleaning market. Here you will find a selection of our research papers and articles covering a wide range of topics within ultrasonic cleaning and the technology surrounding it.

Paper 1

2D modeling of an ultrasonic cleaning vessel – A finite element approach.

Presented at the International Association for Science and Technology Development (IASTED) international conference on Modeling, Identification and Control (Innsbruck, Austria, February 16-18th 2005)
Published in the proceedings of the IASTED international conference on Modeling, Identification and Control

This paper details the initial use of the finite element method to create a numerical model of an ultrasonic cleaner. As a first step to realizing a full 3D model of an ultrasonic cleaner, a 2 dimensional slice along the center axis of an ultrasonic tank is simulated using a modified version of the wave equation. Numerical simulation of ultrasonic cleaning vessels will eventually lead to an improved design methodology and better homogeneity in the ultrasonic cleaning field. The model is verified using two independent practical tests and the results are found to be in good agreement. Some small variation between the simulation and the practical results is found and possible explanations for these differences are put forward.

Paper 2

Finite element simulation of a long Narrow Workload Immersed in an Ultrasonic Cleaning Bath: Practical comparisons and implications for cleaning efficacy.

Presented to the IEEE ultrasonics, ferroelectrics and frequency control (UFFC) groups annual symposium (Rotterdam, Netherlands September 18-21st)
Published in the Proceedings of the IEEE international ultrasonics symposium 2005.

The IEEE ultrasonics symposium represents the highest level of academic work in the ultrasonics field. The paper presented here again used the finite element technique developed to simulate the effects of immersing a work load into an ultrasonic bath. The changes in the ultrasonic field noted due to the introduction of an object have implications for the design of ultrasonic baths, the orientation of workloads and perhaps the future positioning of transducers.

Paper 3

A 2D finite Element analysis of an Ultrasonic Cleaning Vessel – Results and Comparisons

Accepted for publication in the International Journal of Modeling and Simulation on September the 8th 2005 (awaiting published date)

This paper was invited as an expanded version of the conference paper presented to the IASTED modeling, identification and control conference earlier this year. The paper details in greater depth the basis of the simulation technique used, expands on the results gained and discusses the implications in greater detail.

Paper 4

Effects of non-symmetric geometry on bulk cavitation fields – Finite element simulation and practical results.

Presented at the EUROSIS European modeling and simulation (ESM) conference (Porto, Portugal October 16-24th 2005)
Published in the proceedings of the EUROSIS ESM conference 2005

During some previous testing, a difference in the ultrasonic field between one side of a tank and another had been noticed that wasn’t picked up on the simulation. Further investigation revealed that the presence of a drainage hole on the base of the tank was responsible. This paper simulated the existence of non-symmetrical features such as drainage holes and noted the effect on the subsequent ultrasonic field. The results have implications for the positioning of features on ultrasonic vessels and show the importance of a proper design methodology.
