Climate Driven Water Table Changes and Their Influence on Liquefaction Response of Integral Bridges

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Integral abutment bridges (IABs) eliminate bearings and joints but transfer seismic demand directly into the surrounding soil, making their response highly sensitive to groundwater conditions and soil–structure interaction. This study presents a 60 g centrifuge testing programme on single‐span IABs designed to isolate the influence of water ...

Flow Characteristics and Response Surface Methodology‐Based Pressure‐Loss Prediction Models for the Reverse Circulation Converter in Double‐Wall Drill Pipes

Energy Science &Engineering, EarlyView.
Flow characteristics and pressure loss mechanisms of a reverse circulation converter in dual‐wall drill pipes are systematically investigated using CFD and response surface methodology. The results reveal the dominant role of inertial dissipation and provide a predictive framework for optimizing converter design and operational parameters. ABSTRACT The

Influence of Structural and Environmental Parameters on Solar Air Collector Performance

Energy Science &Engineering, EarlyView.
Increasing air gap depth and mass flow rate significantly enhances the thermal performance of solar air collectors, with optimal performance achieved at an 8.5 cm air gap and 0.01318 kg/s mass flow rate. Air gap depth is identified as the dominant factor influencing system efficiency.

Characteristics Analysis and Stage Division of Class Ⅰ Gas Hydrate Deposit Developed by Vertical Well and Depressurization Based on Numerical Analysis

Energy Science &Engineering, EarlyView.
The production process can be divided into two stages according to the relationship between the gas production rate and the decomposition gas rate. The ratio of cumulative decomposition gas to cumulative gas production can be used to evaluate the contribution of the gas hydrate layer.
