Researcher in temperature measurements of two-phase flows - Hiring in process/Finished, not possible to apply

The Division of Combustion Physics is well-established and internationally recognized for excellence in the measurement and development of combustion applications related to ground and aerospace combustion engines and energy production. The Department of Physics conducts a wide array of research, together with other departments within the Faculty of Engineering. Our research facility was built in 2001 and currently supports the work of around 50 researchers. www.forbrf.lth.se/english/

Subject description
The proposed research work consists in determining the temperature field of two-phase flow systems by means of advanced imaging and laser-based diagnostic techniques. Two types of flows will be investigated:

1. The combustion of metal particles
2. The evaporation of heated droplets from atomizing sprays

Work duties
In this research work the temperature field of two-phase flow systems will be investigated including the combustion of metal particles and the evaporation of  heated droplets from atomizing sprays.

For the measurement of liquid temperature in atomizing sprays, a method that combines two-color LIF thermometry together with Structured Laser Illumination Planar Imaging (SLIPI) will be used. This work will focus on deducing the precision and accuracy of the 2D temperature measurements and applying the approach for spray drying applications.

For the combusting metal particles, various approaches involving the detection of spectral bands of the black body radiation will be tested and applied using double-frame sCMOS and/or high-speed cameras. For the case of highly seeded metal particles, the SLIPI technique will also be tested and applied to analyze the particle flow.

Both macroscopic imaging (viewed areas in the order of ~5 cm) and microscopic imaging (viewed areas in the order of ~5 mm) will be used during this project.

Detailed description of the work duties:

• Research within the subject area
• Supervision of degree projects and doctoral students
• Collaboration with industry and wider society
• Administration related to the work duties listed above
