WebApr 5, 2024 · Aerodynamics plays a crucial role in the efficiency of an electric car, and it is measured by the coefficient of drag (Cd) which indicates how easily air flows around the … The aerodynamic design of cars has evolved from the 1920s to the end of the 20th century. This change in design from a blunt body to a more streamlined body reduced the drag coefficient from about 0.95 to 0.30. Time history of cars' aerodynamic drag in comparison to change in geometry of streamlined bodies … See more In fluid dynamics, the drag coefficient (commonly denoted as: $${\displaystyle c_{\mathrm {d} }}$$, $${\displaystyle c_{x}}$$ or $${\displaystyle c_{\rm {w}}}$$) is a dimensionless quantity that is used to quantify the See more The drag equation $${\displaystyle F_{\rm {d}}={\tfrac {1}{2}}\rho u^{2}c_{\rm {d}}A}$$ is essentially a statement that the drag force on any object is proportional to the density of the fluid and proportional to the square of the relative See more Concept The force between a fluid and a body, when there is relative motion, can only be transmitted by … See more The drag coefficient $${\displaystyle c_{\mathrm {d} }}$$ is defined as where: • See more General In general, $${\displaystyle c_{\mathrm {d} }}$$ is not an absolute constant for a given body shape. It varies with the speed of airflow (or more generally with Reynolds number $${\displaystyle \mathrm {Re} }$$).

WebMay 13, 2024 · The drag coefficient is a number which engineers use to model all of the complex dependencies of drag on shape and flow conditions. The drag coefficient Cd is equal to the drag D divided by the quantity: density r times reference area A times one half of the velocity V squared. Cd = D / (.5 * r * V^2 * A) WebApr 3, 2015 · The lower the drag coefficient of an object, the less aerodynamic or hydrodynamic drag occurs. In terms of a car, the lower the drag coefficient, the more efficient the car is. As well as affecting the top … WebAerodynamic drag reduction plays an important part in achieving fuel consumption targets.
