Imperial College Acoustics Engineer Takes Top Award

Imperial College London88, London, United Kingdom

Proposal for an advanced ultrasonic measuring device is awarded prize

A mechanical engineering researcher who is developing an advanced ultrasonic sensor has been honoured at an award ceremony this month.

Acoustician Dr Frederic Cegla , from Imperial College London, was recognised by the Institute of Acoustics for Innovation in Acoustical Engineering (17 October). The Award celebrates the contribution of young acoustical engineers in British industry.

Dr Cegla works in the Department of Mechanical Engineering’s Non-Destructive Testing Group. His project on ‘Ultrasonic Thickness Monitoring in Harsh Environments’ received First Runner Up.

His project describes the development of a robust ultrasonic ‘acoustic cable’ which allows measurements to be taken in environments that are constantly subjected to harsh conditions.

Dr Cegla said his device would be useful for taking measurements from functioning plant equipment in, for example, nuclear reactors, power plants and chemical plants.

“For safety reasons, it is important to constantly monitor industrial plants because in the long term they suffer from fatigue, corrosion and other processes that degrade their structures. Current methods involving lasers are time consuming and costly, the ‘acoustic cable’ provides a durable and cost effective solution for monitoring the integrity of structures.”

Dr Cegla’s new device will transmit ultrasonic signals from a transducer, a device for converting energy from one form to another, along an ‘acoustic cable’ to a measurement zone. This method allows the sensitive transducer to be placed in a safe environment at one end of the cable, while the other end reaches into the harsh measurement zone. The ultrasonic signals are sent along the robust cable back to the transducer for recording.

On accepting his award, Dr Cegla said: “I am delighted by this win and feel very happy to be recognised for my work. This prize not only brings pleasure to me and the people that supported me, but will also help to further the outcomes of my work and its applications in the real world.”

The Institute of Acoustics is the UK's professional body for those working in acoustics, noise and vibration. It was formed in 1974 from the amalgamation of the Acoustics Group of the Institute of Physics and the British Acoustical Society. The Institute of Acoustics is a nominated body of the Engineering Council, offering registration at Chartered and Incorporated Engineer levels.
