Abstract

The invention relates to a method for predicting gate opening type density flow separation depth in a linear stratified water environment. The method includes the following steps that firstly, related topographic data and water density data of a target research area are obtained; secondly, parameters are determined, wherein the parameters include environment water buoyancy frequency, the relative stratification degree of density flow inflow portion environment water, inflow speed of density flow and inflow unit discharge flow of density flow; thirdly, the data obtained in the first step and the data obtained in the second step are substituted into a gate opening type density flow separation depth prediction model (please see the model in the description), and the prediction value of the gate opening type density flow separation depth in the linear stratified water environment is calculated. The method for predicting the gate opening type density flow separation depth in the linear stratified water environment is simple in mode, accurate, efficient and capable of being used for quickly judging the invasion depth of density flow.

Description

Technical field [0001] The invention belongs to the field of density flow research, and specifically relates to a method for predicting the separation depth of a gate-opening type density flow in a linear stratified water environment. Background technique [0002] Density flow usually refers to when two or more fluids with different densities are in contact with each other, the difference in density causes one of the fluids to flow along the interface, and does not mix with other fluids globally during the flow. Movement phenomenon. The motion characteristics of density currents in a stratified environment is one of the important research topics in ocean, atmosphere and other disciplines. In nature, fluid density differences caused by changes in temperature and salinity are common. For a long time, domestic and foreign research on density flow has mainly focused on uniform water environment, but density flow is mostly formed and developed in a stratified environment, such as tur...
