Hybrid Oxygen Enrichment and Preheating Strategy for Performance Recovery in Ultra‐Lean Micro–Trapped Vortex Combustors

Energy Science &Engineering, EarlyView.
Ultra‐lean H2 micro‐combustor performance is boosted through regulated O2 enrichment and inlet preheating. A 16‐case Taguchi study (ϕ = 0.3) shows: controlled enrichment and heating increase radiative output and efficiency, but excessive O2/temperature causes flashback.

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.

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.
