What is aerodynamics? Effects and how to optimize them

One of the factors that affect cycling is aerodynamics. Therefore, some companies have designed bicycles that apply this aerodynamics to optimize the speed of the riders. Here, Tnhelearning.edu.vn will answer your questions about aerodynamics through this article!

What is aerodynamics?

Aerodynamics is the study of the properties and elements of moving air and the interaction between air and solids moving through it, involving CFD (computational fluid dynamics), computational dynamics fluid science, aerodynamic problems in engineering, simulation of the effects of heat flow in processes.

Effects of aerodynamics on cycling

In cycling, there are two main factors that affect your cycling, wind resistance and gravity. In the process of cycling, there are always three wind directions that affect the most, which are crosswind, crosswind and oblique wind. Even if you are cycling on a windless day, you are actually creating wind force because the faster you pedal, the more wind resistance increases.

For example, at speeds of more than 9 mph, wind resistance has already begun to be generated, over time the velocity increases to about 30 mph, 90% of your fitness gradually shifts to drag. more wind, which means you have to lose a lot of strength to fight the “four sides” of the wind.

Aerodynamic optimization factors

There are many ways to optimize cycling aerodynamics, helping you achieve the best speed. These are the 4 most basic factors for optimizing aerodynamics:

Cycling posture:

According to the experience of the champions, the best sitting position to minimize wind resistance is to crouch low, pressing the elbows close to the handlebars to help reduce the interaction between the front obstacle and the wind.

Aerodynamic bike:

Aerodynamic bicycles are likened to the most advanced and classy bicycles available today because they not only possess a “terrible” configuration but also an aerodynamic design structure to bring a high-speed experience. dominant.

Aerodynamic helmet:

This helmet will help you optimize your performance more than conventional hat models. Nowadays, dynamic models of hats are much improved in terms of design and quality and most importantly, safety and comfort when using.

Aerodynamic wheel:

Depending on the line of aerodynamic wheels (deep wheels), the diameter can be from 60 mm to 90 mm. Usually aerodynamic wheels tend to be nicer and the rims are deep to easily cut the crosswinds during cycling, saving up to 48 seconds / 40 km compared to other conventional wheels.

Above are the basic concepts of aerodynamics and their effects on cycling. Hope this article gives you more knowledge to choose a car model that is right for you.
