Pressure drag is caused by the air particles being more compressed (pushed together) on the front-facing surfaces and more spaced out on the back surfaces. This is caused when the layers of air separate away from the surface and begin to swirl – this is called turbulent flow. Note how the wing shape reduces this.
An airfoil is a surface designed to obtain lift from the air through which it moves. Thus, it can be stated that any part of the aircraft that converts air resistance into lift is an airfoil. The profile of a conventional wing is an excellent example of an airfoil. Notice that the top surface of the wing profile has greater curvature than the lower surface. The difference in curvature of the upper and lower surfaces of the wing builds up the lift force. Air flowing over the top surface of the wing must reach the trailing edge of
Simulation is the best tool to lead the innovation associated with aerospace and defense industry trends.
Inspired by VW's ARVW concept, we look at the cars with tiny drag coefficients.
Recently formula 1 race car for 2021 has been annoucned. Significant changes have been made in the design of the F1 2021 car e.g. simplified front wings, sweeping bodywork, bigger rear wings, simplified suspension etc. How will that impact the aerodynamics to answer this question I have done aerodynamics analysis of F1 2021 concept race car. Some initial results are included in this project. Simulation is performed using ANSYS CFX. Around 18 million mesh cells are used in this analysis. For capturing turbulence SST turbulence model is used. More details and short PDF report will be added shortly. ANSYS CFX case file also included for download. Note: These are initial results based on a not very accurate 3D model of F1 car, more advanced results will follow in near future based on more accurate 3D model.

An easy introduction to aerodynamic concepts like boundary layer and drag.
Thrust, drag, lift, and weight are forces that act upon all aircraft in flight. Understanding how these forces work and knowing how to contr...
You occasionally see very pretty photos of contrails, like this one: Very pretty. But what is it? It’s clearly not a regular exhaust contrail, as the trail seems to start actually ON the wing, and it has a weird rainbow effect you don’t often find in exhaust contrails. It’s actually an aerodynamic contrail. It’s formed …

Today I found out why golf balls have dimples. It turns out, somewhat counter intuitively, those dimples significantly decrease the drag on the golf ball as it flies through the air, compared to a smooth ball. Not only that, but they also increases the lift somewhat. These two things combined can make the golf ball go as much as three [...]
