Abstract

The invention provides an artificial waterfall landscape design active control method based on steam-doped characteristic simulation. The method comprises the following steps: establishing a broad-crested weir waterfall model; calculating the flow speeds, flow rates and flow forms of waterfalls with different fluid heights by use of flow 3D software in CFD (computational fluid dynamics); determining the optimal fluid height range on an endowed model according the flow forms of the waterfalls with different fluid heights; and determining the height of the broad-crested weir waterfall model according to the optimal fluid height range. By virtue of three-dimensional numerical simulation, the water flow rate is regulated, so that an inferior landscape is prevented from being formed during a low water period, and an optimal landscape effect of each waterfall section is ensured on the premise of ensuring each flow rate; furthermore, the flow forms of the waterfalls and the drop positions of waterfall currents can be predicated according to the water flow rates; by virtue of reversely controlling the calculation condition through waterfall landscape current, design is supervised, the form is optimized and great convenience is provided for construction.

Description

technical field [0001] The invention relates to an active control method for artificial waterfall landscape design. In particular, it relates to an artificial waterfall landscape based on the simulation of water-air mixing characteristics for water-air multiphase waterfall landscapes that are used in landscape hydraulics for waterfall postures and flow states under different flow rates and include the entire process of continuous-intermittent-water-air mixing Design active control methods. Background technique [0002] Ecological hydraulics and landscape hydraulics are currently emerging hot topics in international research, and are an emerging interdisciplinary subject that interacts between hydrodynamics and ecological landscape theory. Judging from the current research status, the research objects of landscape hydraulics are generally large-scale water conservancy landscapes in complex real environments, and the calculation requirements of its hydraulic characteristics a...
