An airfoil is the cross-sectional shape of the wing of an airplane or a propeller blade. The airfoil body is designed to mainly produce two aerodynamic forces: (1) perpendicular to the free stream flow, which is called the lift force, and (2) a resistive force in the direction of the free stream flow, which is called the drag force. The airfoil shape, its surface area, and angle of attack play an important role in deciding the magnitude of these aerodynamic forces on the airfoil. When designing an airfoil, the best compromise should be obtained between the lift and drag forces at different free stream conditions. Engineering simulations, mainly CFD, help designers understand the effect of changing different parameters on these aerodynamic forces acting on the airfoil.

This SimCafe course was developed by Dr. Rajesh Bhaskaran, Swanson Director of Engineering Simulation at Cornell University, and Benjamin J Mullen in partnership with Ansys. It serves as an e-learning resource to integrate industry-standard simulation tools into courses and provides a resource for supplementary learning outside the classroom. In this course, we will learn to conduct a CFD analysis of the NACA 0012 Airfoil at 6 degrees angle of attack placed inside a wind tunnel by following the end-to-end workflow using Ansys Workbench. We will learn to model the flow around this airfoil and post-process the results to estimate both lift and drag forces.

It is critical to understand and study the distribution of the aerodynamic forces for the stability of the tall structures such as chimneys. These forces can be estimated with the help of engineering simulations. In this SimCafe Course, we consider a canonical problem of steady flow past a cylinder to understand the aerodynamic effects of wind on chimneys using Ansys Workbench.

The study of blood flow through arteries can help understand the level of plaque formation inside the artery. In such scenarios, it is important to understand the velocity, pressure, and wall shear stress to determine the efficiency of blood flow. In this SimCafe course, we learn to model the blood flow through the artery by following the end-to-end workflow in Ansys Fluent.

Due to the fluid properties (viscosity in particular), external flows show different characteristics near the object’s surface compared to regions away from the object. The formation of a boundary layer, which is a thin narrow viscous region near the object’s surface, is one common element in all external viscous flows. Simulations help us calculate these forces and make the required design changes to obtain higher lift and minimize drag. In this Sim Cafe course, we consider a canonical problem of steady flow over a flat plate to understand the aerodynamic effects on a flat surface using Ansys Workbench.
