Aerodynamics and Aerospace Engineering

What is Aerodynamics?

Aerodynamics is the way air moves around things. The rules of aerodynamics explain how an airplane can fly. Anything that moves through air reacts to aerodynamics. A rocket blasting off the launch pad and a kite in the sky react to aerodynamics. Aerodynamics even acts on cars since air flows around cars. The four prominent forces in Aerodynamics are Lift, weight, thrust, and Drag. These forces make an object move up and down and faster or slower. The amount of each force that exists over a body defines how the object moves through the air.

Aerodynamics

Understanding the motion of air around an object (often called a flow field) enables calculating forces and moments acting on the object. As was mentioned above, in many aerodynamics problems, the forces of interest are the forces of flight: Lift, Drag, thrust, and weight. Lift and Drag are aerodynamic forces, i.e., forces due to airflow over a solid body. Calculation of these quantities is often based on the assumption that the flow field behaves as a continuum. Continuum flow fields are characterized by properties such as flow velocity, pressure, density, and temperature. These properties can be directly or indirectly measured in aerodynamics experiments or CFD (Computational Fluid Dynamics) methods.

CFD simulation in Aerodynamics and Aerospace Engineering

The primary target of CFD in the aerodynamics field is to predict velocity and pressure distribution around bodies (like cars, birds, and airplanes, etc.) and, consequently, determine the pressure, Drag, lift, and moment coefficient. Utilizing this powerful tool, an aerodynamics or aerospace engineer can carry out the best and most optimum design of a car, airplane, space shuttles, etc., without fabricating a prototype to experiment on and therefore, reducing expenses to a high degree. For example, in designing aircraft, we tend to minimize Drag force and increase the lift force. In other words, we tend to increase the Lift to drag force ratio to increase the efficiency of our design. Another case is designing a wind turbine. In contrast to the previous example, we tend to increase the power coefficient related to the moment coefficient, which is related to Drag and force magnitude simultaneously.
