Overview

PhD candidate position in Thermohydrodynamic numerical and experimental study to increase the performance of air source heat pumps

Open application for a doctoral candidate in Mechanical Engineering
The doctoral candidate position is available in the Environmental Engineering faculty Building Energetics department. Applicants interested in other research topics related to renewable energy technologies are also welcome to apply.

Research topic description
To reduce climate change, and increase energy efficiency, and renewable energy usage in buildings, heat pumps are being discovered as one of the solutions that are increasingly being applied. The buildings sector is projected to have zero CO2 emissions by 2050. Air source heat pumps are becoming an increasingly popular source of heat energy for building heating/cooling. However, their operation is affected by outdoor and indoor conditions; the established operating strategy; this is especially noticeable in countries with colder climates when the problem of evaporator surface freezing is encountered. This occurs at lower outdoor temperatures and high relative humidity (typically > 80%). This problem is addressed in a variety of ways, but adaptive solutions typically reduce the heat pump efficiency (coefficient of performance – COP). The development of air-source heat pumps, their components (e.g., evaporator) and the combination of options with other renewable energy transformation technologies are becoming important to achieve lower energy consumption and lower operating costs. Numerical studies of the evaporator surface using computational fluid dynamics and experimental studies would provide more detailed recommendations for increasing the efficiency of the equipment from a thermo-hydrodynamic point of view. The research goal is to develop a methodology to improve the energy efficiency of the air source heat pump by analysing the processes in the evaporator component using computational fluid dynamics and experiments.

The selected candidate will work on the PhD thesis under the supervision of dr. Giedrė Streckienė. The successful applicant will have to attend scientific conferences, meetings and internships in the other universities.

Requirements
• Required background: mechanical engineering or energetics background, experience with renewable energy technologies operation, thermodynamics.
• Expected skills and knowledge: experience with computational fluid dynamics (e.g. ANSYS Fluent or other related).
It is a prerequisite you can be present at and accessible to the institution daily.

For more information
Shortlisted candidates will be invited for an interview. The position may not be opened if no qualified candidate is found. Additional information regarding the post may be obtained from dr. Giedrė Streckienė, e-mail: giedre.streckiene@vilniustech.lt

Programme structure

The PhD programme consists of:
· Independent research under supervision;
· Courses for PhD students (approximately 30 ECTS credits);
· Participation in research networks, including placements at other, primarily foreign, research institutions;
· Teaching or another form of knowledge dissemination, which is related to the PhD topic when possible;
