Research on the External Fluid Flow of a Round Cylinder with CFD

Abstract

Fluid mechanics is a frequently applied discipline, and technology advancements have substantially improved how engineers’ approach and solve issues, and one of them is CFD. The purpose of the study was to evaluate how closely CFD adheres to accepted engineering principles. Selected CFD conducts computations to compare the magnitude and direction of drag coefficient changes under conditions of rising Reynolds number by simulating conditions in a wind tunnel to gather data on the object's reaction to fluid velocity. Within this range, the drag coefficient decreases with increasing Reynolds number. The simulated Reynolds number and drag coefficient do have a consistent relationship with the facts.
