Summary: In this study, the effects of different pitch of internal helical heat fins on methane steam reforming in a packed bed reactor were investigated. It was found that larger pitch increased the outlet mass flow and velocity disturbance by 9.5% and 382.3% respectively, but also brought higher flow resistance. The internal helical heat fins improved the fluid temperature and reduced the thermal resistance, with a temperature increase of 19.2 K and a thermal resistance decrease of 43.1% compared to the normal packed bed. The highest efficiency was achieved when the pitch was 120 mm, with an increase of 42.3%. Although the internal helical heat fins increased the reactor cost due to structural complexity, the total cost decreased. The lowest total cost was achieved when the pitch was 120 mm, with a decrease of 24.6% to about 1.6 USD/kg.

Summary: This paper investigates the hydrodynamics of a bubbling fluidized bed gasifier using static and rotating perforated air distributor plates. The results show that the rotational velocity of the distributor plate has the highest impact on the fluidized bed for lower superficial velocities, shallow initial depth, and the maximum rotational velocity of the plate. The use of a rotating distributor plate increases the pressure drop across the bed and decreases the minimum fluidization velocity compared to a static plate distributor. The bed height rise is also higher for static plate distributors due to the dominant axial component of air velocity. Furthermore, the pressure fluctuations within the bed are significantly reduced when using a rotating distributor plate.

Summary: Here, we report a highly conductive, robust, and innovative Gd and Pr multi-doped ceria (GPDC) coating to enhance the ORR kinetics and stability against Cr poisoning of the state-of-the-art LSCF cathode. The GPDC coating significantly improves the ORR kinetics by improving the surface of the LSCF cathode and shows a two-fold increase in electrochemical performance compared to the bare LSCF cathode. It also exhibits outstanding stability in an accelerated Cr poisoning test, attributed to the alleviation of SrCrO4 formation. Both relaxation time-based analysis and experimental results confirm that the GPDC coating enhances the ORR activity and Cr tolerance of the LSCF cathode.

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.
