Summary: This study investigates the effects of pore structure, temperature, and thermal expansion on the effective thermal conductivities of CaCO3 and CaO particles in a CSP-CaL plant. The results show that pore structure has a negative effect on the thermal conductivities of both particles, especially for larger theoretical conductivities. In addition, the effective thermal conductivities at low temperature are lower than those at high temperature due to their different thermophysical properties. Thermal expansion caused by high temperature leads to a significant reduction in the effective thermal conductivities of both particles.

Summary: This study investigates the synergetic effect of complex pore structures and different operating conditions on the micro-flow diffusion mass transfer performance inside CaO materials. It is found that the effective gas diffusion coefficient increases with increasing porosity, and decreases with an increase in fractal dimension. A prediction model based on machine learning is proposed to better understand this synergetic effect, which shows better performance than the traditional Maxwell model. This model may provide theoretical guidance for the design of Ca-based materials with high performance, and it could also be used in reactor design or system thermodynamic investigations.

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.
