Numerical Results — Lesson 7

Part 1: Contours

This lesson covers the process of postprocessing in Ansys Fluent® fluid simulation software. It explains how to visualize the pressure and velocity fields in the flow domain using contour plots. The lesson also discusses the significance of the low velocity stagnation region in front of the cylinder, the high-pressure region from the stagnation points, and the low pressure and high velocity region as the flow moves around the cylinder. The lesson further elaborates on the concept of form drag and the impact of viscous forces on the cylinder. The lesson concludes by demonstrating how to view multiple plots simultaneously for a comprehensive analysis.

Part 2: Streamlines

This lesson covers the process of creating streamline visualizations in Ansys. The lesson explains how to select path lines, create new streamlines, and color them by velocity. The lesson also demonstrates how to define a line for fluid particles to determine their path and how to create a visualization of the interior circle. The lesson further explains how to combine all visualizations into a single one for a complete streamline picture.
