Investigation of the effect of tornado wind force velocity range ratio on a cylindrical structure using CFD

Abstract EN

Based on the usage of CFD, a Composite Vortex Rankine Model (RCVM) is employed to generate a real tornado-like velocity distribution.

According to the numerical simulation results, the velocity range ratio can be thought of as a ratio ranging from 1 to 6.

The tornado-like flow occurs when V / Vt = 1 to 3, and the tornado has a conical shape with the upper part tilted forward.

Furthermore, the ratio (V / Vt) of a true tornado range from 1 to 6.

The tornado simulation results from this study are relatively compatible with earlier studies in terms of the influence of modifying the V/Vt ratio on the tornado structure.

When 1 to V / Vt = 3, a tornado-like flow was discovered.
