Professor Ian Smith was awarded a Fellowship of the Royal Academy of Engineering recently in recognition of his outstanding contribution to engineering over more than 50 years.
Professor Smith, part of the University of London's School of Mathematics, Computer Science and Engineering, has pioneered research into 'power recovery from low-grade heat sources, involving compressible flow effects, alternative working fluids to steam, and novel two-phase compression and expansion cycles.'
Also recognised was his directorship of the Centre for Positive Displacement Compressor* Technology at the university.
Positive displacement compressors
Positive displacement compressors draw in and capture a volume of air in a chamber, then reduce the volume of the chamber to compress the air. Reciprocating Piston Compressors, Rotary Screw Compressors, Rotary Vane Compressors, and Scroll Compressors are all positive displacement compressors.
