Design and Experimental Study of Pressure Maintenance and Temperature Control System for Hydrate Pressure Core Processing Device

Energy Science &Engineering, EarlyView.
This paper presents a hydrate pressure core processing device integrated with a high‐precision active control system to perform nondestructive transfer, cutting, and analysis. To address the limitations of slow dynamic response and high thermal inertia in traditional passive systems, a differentiated control scheme is implemented.

Waste to Hydrogen: Transforming Food Waste Into Biohythane (Bio‐H2 + Bio‐CH4) in a Two‐Stage Reactor With the Aid of a Metal‐Ion Catalyst

Energy Science &Engineering, EarlyView.
This study demonstrates a two‐stage catalytic bioreactor system that converts real food waste into high‐purity biohydrogen and biohythane. In Stage‐1, an enriched Clostridium thermocellum culture combined with Ni2+─Fe2+ bimetallic catalysis enhances hydrolysis efficiency and hydrogenase activity, resulting in a 77% increase in H2 yield and 75.8% purity

Unsteady Flow Behavior and Radial Force Analysis of a Side Channel Pump Under Different Blade Tip Cutting Angles Using Computational Fluid Dynamics

Energy Science &Engineering, EarlyView.
The Radial Force (RF) distribution under different cutting angles is presented in Figure 1. Generally, the distribution of RF displays divergence across different flow conditions. The pattern of force distribution reveals a total of 24 peaks, which corresponds to the number of blades of the impeller of the SCP.
