This PhD project aims to understand and model the superheat limit of liquid evaporation which underpins the phenomena of explosive boiling. Explosive boiling usually occurs when a low temperature liquid is injected into a high temperature liquid. The high pressure generated during the process in practical applications can be undesirable from the safety point of view but could potentially be very useful for power generation. Therefore, being able to understand and model the superheat limit can be important for the safety and efficiency of energy systems where explosive boiling happens.
This is an opportunity for a world-class research training at Loughborough University, including opportunities to explore the state-of-art optical diagnostic facilities, and attend international conferences. The successful applicant will be expected to be an integral part of a multi-discipline research team with strong collaborations with academics and industries worldwide.
The research will include: 1. Systematic review of the existing physical models for explosive boiling and relevant phase change and hydrodynamic instability theories; 2. Experimental quantification of the superheat limit of single and multi-component liquids and the consequential explosive boiling process by setting a high-speed optical diagnostic system. 3. Theoretical analysis of the superheat limit and the instabilities during the explosive boiling process.
