However, the limited urban rooftop area and high building facade cost hinder the onsite installation of PV systems. To address this, pavement-integrated photovoltaic/thermal (PIPV(T)) technology, which harvests solar energy from the road, shows promise. This study proposes and verifies 2D finite element PIPV(T) models, and conducts parametric analyses on system designs, weather conditions, and ground boundary conditions. The results demonstrate the significance of factors such as water tank volume and fluid velocity in improving thermal efficiency.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
