Seismic Fragility Analysis of Containment Structures in Nuclear Power Plants Considering Alkali‐Silica Reaction

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study quantifies the influence of alkali‐silica reaction (ASR) on the seismic fragility of prestressed concrete containment structures in nuclear power plants (NPPs). Global collapse was considered as the governing failure mode to maintain consistency with current risk assessment frameworks, and was captured using a finite element model ...

Optimization of Multi-Objective Problems for Sailfish-Shaped Airfoils Based on the Multi-Island Genetic Algorithm

Machines
This article uses the sailfish outline as an airfoil profile to create a dual vertical-axis water turbine model for capturing wave and tidal current energy. A parametric water turbine model is built with the shape function perturbation and characteristic

Design of HAWT Rotor for Non‐Uniform Inflow Conditions: A Theoretical and Experimental Approach for Shear Flow

Energy Science &Engineering, EarlyView.
This paper aims to provide a robust design approach for HAWTs operating in shear flow. This study fills a critical research gap by integrating BEM and vortex theories for blade design in non‐homogeneous inflow conditions. The authors of the paper made an effort to develop and test an experimentally unsophisticated model of a turbine working in shear ...

Effect of Axial Agitator Configuration (Up-Pumping, Down-Pumping, Reverse Rotation) on Flow Patterns Generated in Stirred Vessels [PDF]

, 2001
Single phase turbulent flow in a tank stirred with two different axial impellers - a pitched blade turbine (PBT) and a Mixel TT (MTT)- has been studied using Laser Doppler Velocimetry. The effect of the agitator configuration, i.e.

Two‐Layer Optimal Control Strategy of Thermal Power Unit Coupled With Hybrid Energy Storage System in Frequency Regulation

Energy Science &Engineering, EarlyView.
An optimized two‐layer TPU‐HESS operation strategy enables adaptive power allocation, mitigates regulation delay, and enhances AGC performance by 6.4% over conventional control methods. ABSTRACT With the growing penetration of renewable energy, its intermittency and fluctuation have imposed increasingly stringent regulation requirements on thermal ...
