The SHRL have been awarded a £1.3m EPSRC research grant to study the deformation of microscopic fuel droplets.
We are seeking to recruit two EPSRC Research Fellows.
We are currently offering a fully funded PhD studentship on laser diagnostics for sprays.

Theory
High speed imaging allows the capture of the entirety of very fast events so that they can be replayed at a much slower speed. It is particularly useful for the study of sprays and flames development. High speed imaging can either be performed using global illumination, giving a line of sight view of the spray or flame, or using a laser sheet allowing the viewing of a slice of the studied object. Global illumination has the advantage of being cheap as it only requires a powerful lamp but can lead to difficulties in interpreting images due to the projection of a 3 dimensional image onto a 2-d plane. Laser sheet illumination is much more expensive as it requires either a powerful continuous laser or a very fast pulsed laser but has the advantage of giving very good spatial resolution.
The university owns a high-speed digital camera (up to 140000 frames per seconds at reduced resolution), and spotlights for global illumination. For laser sheet illumination, the university has access the EPSRC loan pool.
