Cylinder flow 3900

WebJul 1, 2024 · Unsteady flow past a cylinder (Re=3900) was computed using large eddy simulation (LES) by OpenFOAM. The study includes the prediction of drag and lift coefficient, and pressure distribution around the cylinder. During the simulation, the one-equation sub-grid scale (SGS) model was applied. LES numerical results were compared … WebThe experiment used two sets of cylinders. The first set was designed to study heat transfer; hollow cylinders of 66 mm diameter and 0.1 mm thickness are made of steel sheets. The model’s structure is shown in Figure 1. Figure 1.
