Abstract

The present invention relates to a numerical simulation method of the motion characteristics of hydrothermal plumes based on Fluent software. Specifically: 1. Construct a custom function; 2. Establish a dynamic model; 3. Divide the grid; 4. Numerical solution to determine the maximum rise height of the plume and the calculation formula of the neutral buoyancy layer height; 5. Output the solution result. The present invention can simulate the changes in various parameters of the hydrothermal plume, which is helpful to understand the material transport and energy cycle of the ocean; at the same time, compared with traditional deep-sea in-situ measurements, it has the advantages of low cost and complete data. The results show that under the same working conditions, the maximum rise height and the neutral buoyancy layer height of the simulation results compared with the measured results are basically consistent, and the error is less than 5%.
