Embodiment Construction

[0055] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0056] A method for calculating water drop flow in a borderless swimming pool, comprising the following steps:

[0057] A. Use the gambit software to establish the model of the unbounded swimming pool. The width of the swimming pool is 20.0-80.0m, and the height of the water drop is 0.6m. The regular area is divided into a structured grid, and the irregular area is divided into an unstructured grid. The grid skew rate If it is less than 0.8, set the boundary conditions and export the model;

[0058] B. Import the established unbounded swimming pool model into Ansys Fluent software, select the RNG mode of the k-ε model, adjust the under-relaxation factor and initial conditions, start the iterative calculation after initialization, observe the iterative curve at all times, and judge the calculation after the calculation is stable degre...

Abstract

The invention discloses a boundary-free swimming pool water drop flow calculation method. The method comprises the following steps: A, establishing a boundary-free swimming pool model through gambit software; B, importing the established boundary-free swimming pool model into Fluent software, and selecting an RNG mode of a k-[epsilon] model, adjusting an under-relaxation factor and an initial condition, and starting iterative computation after initialization; C, after iterative computation is stable and convergent, extracting mass effective data of all nodes of the middle section, importing the mass effective data into graph processing software Tecplot, adjusting a water volume fraction to 0.95, and adjusting and displaying cloud picture indexes to obtain minimum unit width flow which is the minimum flow when the model water film is not attached to the wall and is not broken; and D, fitting the height and the flow velocity value of the effective node into a curve, and finding out the minimum flow of the water film which is not attached to the wall but not broken when the boundary-free swimming pool with the fixed width runs from the curve. The relation between the width of the swimming pool and the water falling flow when the water tongue is not attached to the wall and is not broken is determined through a numerical simulation technology.

Description

technical field [0001] The invention relates to the technical field of a borderless swimming pool, in particular to a calculation method for water drop flow in a borderless swimming pool. Background technique [0002] The special design of the edge of the swimming pool makes people feel that it has no edge and pool wall, so as to achieve the visual effect of infinite space. Its working principle is to make the static water body move in a directional laminar flow in a limited space, and the swimmer swims against the flow direction of the current. [0003] The falling of the water body in the borderless swimming pool through the top edge of the side wall belongs to the phenomenon of weir flow and water drop. Weir flow refers to the rapid flow phenomenon in which the slow flow on the weir passes through the weir crest overflow; the water flow of the weir crest overflow varies with the ratio of the weir crest thickness δ to the water head H above the weir. Ratio, the weirs are...
