In honor of International Women in Engineering Day 2017, we celebrate the many achievements of Professor Dame Ann Dowling. She is the President of the Royal Academy of Engineering as well as a Professor of Mechanical Engineering and Deputy Vice-Chancellor at the University of Cambridge.
See more on her esteemed career here.
Professor Dowling’s research aims to enable society to have power and transport without environmental damage or excessive noise. There are two main themes, one associated with efficient, low-emission combustion, and the second with understanding, modelling and reducing the noise from cars, helicopters, fixed-wing aircraft and domestic appliances such as vacuum cleaners and fans.
The drive for low emissions is causing aero and industrial gas turbine combustors to operate on the verge of instability. Ann Dowling’s research is aimed at understanding this phenomenon and involves theoretical modelling, computations and experiments. Her team develop techniques predict the onset, frequency and limit cycle amplitudes of the self-excited oscillations that are the result of the instabilities. Both passive and active means of control are investigated, and various successful approaches have been demonstrated.
