Description:

Waste Heat Recovery (WHR) Organic Rankine Cycle (ORC) technologies are gaining increasing attention as a promising solution for decarbonizing the shipping sector and reducing fuel consumption in marine engines. Among the key components of ORC systems, heat exchangers play a critical role in system efficiency, especially due to their compactness and effectiveness. Since they account for 70–80% of the total investment cost and occupy significant volume compared to other system components, optimizing the design of Plate Heat Exchangers (PHE) is essential for improving the overall performance and cost-effectiveness of marine ORC systems.

 

The following work packages (WPs) form the content and tasks of the thesis:

 

WP1: Conduct a comprehensive literature review on modeling and optimization approaches for PHE.

 

WP2: Improve the existing PHE model using the LMTD method developed in MATLAB®. The goal is to determine optimal design parameters that maximize overall heat transfer coefficients while minimizing pressure drops. Optimization will be carried out using a heuristic algorithm, integrated into an existing ORC operation optimization code.

 

WP3: Sensitivity analysis with respect to fixed geometric parameters, flow arrangement and other indicators will be conducted. Optimal PHE design to be determined.
