Subject description

The proposed research work consists in developing and applying some advanced laser imaging techniques for determining the temperature on hot surfaces that are cooled with spray systems. The main goal of this project is to deduce accurately the efficiency of various spray systems for cooling electric motors. Such measurements will be performed by means of novel ultrafast imaging approaches.

Work duties

The main duties involved in a post-doctoral position is to conduct research. Teaching may also be included, but up to no more than 20% of working hours. The position includes the opportunity for three weeks of training in higher education teaching and learning. The purpose of the position is to develop the independence as a researcher and to create the opportunity of further development.

An important issue related to the use of electric motors is the excess of heat that is generated during power-demanding operations. To solve this issue, the use of spray cooling is very promising. This new approach needs to be analyzed.

The work duty of this research project is to analyze in detail the cooling of electric motors using sprays. Accurate temperature measurements of fast cooling systems will be obtained by combining several advanced laser imaging techniques. This includes: 1) Two-color LIF thermometry. 2) Life-time LIP thermometry. 3) Two-photon excitation. 4) Structured illumination. 5) Ultra-high-speed image recording.

Detailed description of the work duties, such as:

• Research within the subject area
• Guidance and co-supervision of doctoral students
• Administration related to the work duties listed above
• Following the planning of the E-COOL project funded by EIC
