Three‐Dimensional Analytical Model of a Free‐Standing Square Rocking Column

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT A three‐dimensional analytical two‐degree‐of‐freedom (2DOF) model is developed to describe the bounded rocking response of free‐standing rigid square columns subjected to bidirectional seismic excitation. The formulation extends Housner's classical planar theory by deriving the full three‐dimensional equations of motion for a column ...

Mass Exchange Flow Process in Side Channel Pumps: Effects of Different Geometrical Parameters

open access: yesEnergy Science &Engineering, EarlyView.
Figure 1 shows the Mass Flow Exchange (MFE) in the impeller at z = 7.5 × 10−3 m at 1.0 Q/QBEP, operating point for impeller scheme 1 (IMP 1), and impeller scheme 2 (IMP 2). The flow begins to exit the impeller at the outer radius and enters at the inner and central radii. IMP 1 exhibits more flow in and out compared to IMP 2. ABSTRACT The functionality

Design of a Hydroelectronic Solar‐Tracking System for Solar Panels

open access: yesEnergy Science &Engineering, EarlyView.
A prototype of a passive solar‐tracking system utilizing buoyant force based on water level was developed, and its MATLAB/Simulink model was implemented. This study is expected to encourage researchers to design solar‐tracking mechanisms using metals with different thermal expansion coefficients, air, oil, and other fluids. ABSTRACT This study presents

Optimized Parameter Extraction in Triple Diode Solar PV Models Using Kookaburra‐based Dwarf Mongoose Approach

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT Improving photovoltaics (PV) system performance through simulation requires accurate PV models. The nonlinear relationship between current and voltage, coupled with incomplete manufacturer data, presents a significant challenge in parameter estimation.
