For accurate results, apply mesh control to the cylindrical face of the liquid jet.
Mesh control refers to specifying different element sizes at different regions in the model. A smaller element size in a region improves the accuracy of results in that region. You can specify mesh control at vertices, edges, faces, and components.
The following procedure is not applied to the model since it takes longer computation time. The results of the study are found to be in reasonable agreement (about 1% error) with those obtained with mesh control.
