Zeotropic mixtures offer a possibility of optimizing organic Rankine cycles (ORCs) efficiencies by matching the working fluid temperature glide to the heat source and sink temperature profiles. However, the use of zeotropic mixtures entails a degradation of the heat transfer coefficient compared to pure fluids, thereby posing attention to the design of heat transfer equipment. Plate heat exchangers (PHEs) offer a suitable solution for the high heat transfer coefficient achieved within their compact design and the possibility to arrange the flow in a counter-current mode, which is essential to achieve thermodynamic glide matching.

The focus of this project will be to model, design and optimize plate heat exchangers to be used as different components of ORCs integrated in different applications. 

The student will be responsible for developing and/or extending an existing modeling framework for coupled cycle and component simulations. 

The impact on the overall cycle performance of both heat transfer and pressure drops for different pure fluids and zeotropic mixtures can be assessed. The framework of the project can also be adjusted and changed according to student’s preferences and own ideas.

We look for students with knowledge of thermodynamics, heat transfer and basic skills in programming.

The project can be framed as a final thesis, special course or others.
