Numerical Results — Lesson 7

Vectors and Contours

This video covers the post-processing of cell center values of primary unknowns to produce useful visualizations in Ansys Fluent® fluid simulation software. It explains how to reopen the Ansys Fluent tool's interface for post-processing and use CFD post, an alternative and older postprocessor. The lesson demonstrates how to visualize velocity vectors and contours, and pressure contours. It also discusses the interpretation of these visualizations, such as identifying the stagnation point, checking the flow around the airfoil profile, and understanding the pressure differences that cause lift. For instance, the lesson shows how to identify a low velocity region due to stagnation and a high velocity region due to fluid movement around the leading edge.

Streamlines and Coefficients

This video covers the process of visualizing streamlines of flow using Ansys Fluent software. It explains two methods of accomplishing this: using contours of the stream function and creating path lines. The video also provides a step-by-step guide on how to select and adjust various settings in the software to achieve the desired visualization. For instance, it explains how to select a range of values for the stream function, how to draw a mesh, and how to create a line/rake for fluid particles. The video further discusses how to interpret the resulting visualizations, such as identifying the stagnation region and understanding the pressure coefficient around the airfoil.
