Abstract The docosane–dodecanol (DE-CP) binary phase change materials (PCMs) were prepared to improve the heat diffusion performance of photovoltaic/thermal (PV/T) system in this work. transition temperature DE-CP matches photovoltaic dissipation requirements, with 60 wt% DE achieving optimal latent 243.8 kJ/kg. Expandable graphite maximizes expansion at 900°C for seconds, resulting high pore volume and adsorption capacity. Incorporating expanded into increases thermal conductivity from...
Abstract Piezoceramic-based ultrasonic transducers have demonstrated the feasibility and effectiveness of functioning as smart aggregates (SAs) to detect damages for concrete structures in laboratory-sized structural members. The restriction its further engineering application is limited propagation distance due large energy loss during wave transmission. Aiming reduce piezoceramic-based sensors, authors proposed a high-performance piezoceramic-enabled SA based on acoustic impedance matching...

As compared conventional cone-shaped nozzle 120° taper angle, amplitudes fluctuation maximum jets increase by 24 37%, respectively, erosion efficiency increases 1 to...
In this study, the numerical investigation of detectability concrete aggregate segregation in circular concrete-filled steel tubulars (CCFST) based on piezoelectric lead zirconate titanate (PZT) measurement is performed. The stress wave propagation core CCFST excited with a surface-mounted PZT actuator studied multi-scale and multi-physical field coupling analysis. effect patches its CFSTs are considered. Numerical modeling technology employed to construct composed randomly distributed...

In this study, the effects of torsion strain and rate on microstructure hardening behavior extruded AZ31 Mg alloy rods are investigated. Torsion deformation can generate abundant extension twins dislocations cause rotation c‐axis toward extrusion direction. These microstructures exhibit gradient distributions along radial direction torsion‐deformed rods. effectively enhance hardness The leads to a distribution in High rates effect via by promoting increment dislocation density.
The extended finite element method (XFEM) is efficient in simulating crack initiation and its evolution process for reinforced-concrete (RC) structures due to ability solve fracture problems. Moreover, the multiscale numerical simulation helps understand global local failure behavior of RC simultaneously. In this study, XFEM-based modeling approach was proposed investigate monotonic hysteretic performance columns. Firstly, two-scale models composed fiber beam elements solid with homogeneous...
In recent years, the development of interface debonding defect detection methods for concrete-filled steel tubes (CFSTs) using stress wave measurement with piezoelectric-lead-zirconate-titanate (PZT) actuator and sensor has received significant attention. Because concrete core in CFSTs is a heterogeneous material randomness at mesoscale, size, position distribution aggregates unavoidably affect propagation PZT response. this study, to efficiently investigate influence mesoscale structure on...
