Modelling Translating Tornado-Like Wind Flow using CFD Simulations

Abstract

This study investigates and compares two different strategies to simulate the translating motion of tornadoes, which are to establish the relative motion between the tornado and the ground, or to move the swirling wind flow directly. To be specific, two approaches based on the two different strategies are applied to model the translating motion of the tornado-like wind flow. By comparing the generated overall and near-ground wind flow with the real-world tornadoes, the proper way to simulate the translation of tornadoes is determined.
