METHOD AND SYSTEM FOR TURBULENT FLOW INTERPRETATION OF TURBULENT FLOW FIELD AROUND HYDRAULIC STRUCTURES

摘要

PURPOSE: A method for analyzing the turbulence of a turbulence field installing a handwork structure and a system thereof are provided to improve the accuracy of turbulence analysis by calculating an eddy viscosity coefficient at a target spot based on the shortest distance and calculating shear stress. CONSTITUTION: An area forming unit(300) forms division areas by dividing a turbulence field into areas. A coefficient calculating unit(400) calculates an eddy viscosity coefficient by using the shortest distance to a handwork structure. A stress analyzing unit(500) calculates shear stress at spots by using the eddy viscosity coefficient. A model building unit(600) builds a numerical model of the turbulence field by using the eddy viscosity coefficient and the shear stress.
