The post holder at Brunel will carry out research which combines cutting-edge experimental techniques that furnish spatiotemporally-resolved diagnostics of the thermal and hydrodynamic fields and data that will be compared with modelling and 3-D high-fidelity numerical simulations performed by our partners. The deep insights generated from the project will be harnessed to provide heat transfer tools that are practically implementable by our industrial partners in order to maximise impact.

The post holder will design, construct, commission and validate an experimental facility and carry out experiments in single and two-phase spray cooling systems. Different working fluids will be used as sprays to provide a sufficient range of thermophysical properties. The spray cooling area will cover the active heat transfer area for maximum cooling and heat transfer data consistency. Smooth and enhanced heat transfer surfaces will be studied. The experiments will correlate single and two-phase heat transfer rates from the surfaces to the fluid properties, spray nozzle diameter and height-surface area ratio, inlet pressure, volume flow rate and surface superheat. A high-speed, high-resolution camera and an imaging system will be used to capture the droplet size distribution and velocities plus the spray drop impact on the liquid film and the heat transfer process.

The data available from the experimental study covering the above parameters giving the heat transfer rates and spray efficiency and their dependence on the control parameters will be compared with the experiments at the University of Edinburgh and the numerical work of Imperial College London to clarify fundamental phenomenal in spray cooling systems. It is expected that the experiments will lead to correlations equations, easy-to-use in industrial spray cooling applications.

Candidates must have or be near completion of a PhD degree in Mechanical, Aerospace or Chemical Engineering with background knowledge in thermal engineering, including experimental techniques. In addition, candidates should have, good communication skills and a good record in disseminating research outputs.
