NUMERICAL ANALYSIS METHOD OF FLUID FLOW TO SIMULATE DRYING/WETTING

摘要

PURPOSE: A method for interpreting a limited element figure of a fluid flow using a dry/wet process is provided to remove a dry element and automatically regenerate the lattice of a wet element by calculating an increase or decrease in the speed of a water level during a calculating time. CONSTITUTION: A water level is predicted. A break point according to the predicted water level is determined as a dry or wet state. A lattice is reconfigured according to the dry or wet state. If the break point is determined as a dry condition, the lattice and the break point is removed in a lattice network. If the break point is determined as a wet condition, the lattice and the break point is included in the lattice network. If the water depth of break point is 0 or is a negative value by comparing the predicted water level and the water depth of the break point, the dry condition is determined.
