RESEARCH ON OPTIMIZATION DESIGN OF ABNORMAL FLIP BUCKET

摘要

This study constructs an optimization model to address ski-jump energy dissipation problems in different reservoir environments. The multi-objective genetic algorithm is applied herein as the calculation method. Due to the influence of ski-jump energy dissipation on the scouring pit in real-life engineering situations, the pressure of water flow at the point of fall influences the depth of the scouring pit, while the kinetic energy of water flow influences its shape. The optimization objective is determined at the minimum water flow pressure at the point of fall, measuring the minimum kinetic energy. The design incorporated two variables to represent the whole abnormal flip bucket, namely overflow width and height of the flip bucket. Boundary conditions were created by the solid boundary and air boundary, as well as the constant inflow rate. The optimal overflow width and height of the flip bucket were calculated through optimal computation, which can minimize the scouring force of water flow as it falls onto the ground. The results obtained provide theoretical references for practical engineering and reduce potential safety hazards. The energy in flip buckets after optimization of water flow can be fully dissipated, creating an ecosystem where water can flow unobstructed. Guiding water flow to water-deficient areas is of great significance in ensuring the long-term protection of environments and ecosystems.
