NUMERICAL SIMULATION SYSTEM AND METHOD FOR ATMOSPHERIC WIND FLOW BY COMPUTATIONAL FLUID DYNAMICS

摘要

The present invention relates to an atmospheric flow field numerical simulation system by using computational fluid dynamics and a method thereof capable of rapidly and efficiently performing fluid analysis and easily mapping wind power resources by setting a wind direction interpretation result according to a same interpretation area into an initial condition (a second initial condition in the present invention) of different wind direction interpretation.
