By the results obtained in the testing procedure, we conclude that a very low drag coefficient automobile body can be altered to contain a workable cooling system without increasing overall drag significantly. The venturi system is a workable method of obtaining the required airflow across the radia...

idea of low and high pressure zones, fluid vectors, and ways they can streamline their parts. In this tutorial you will learn how to find the drag coefficient of a sphere and insert and view plots of velocity. You will also learn the limitations of the Solidworks Flow simulation add-in....
http://en.wikipedia.org/wiki/Drag_coefficientIn fluid dynamics, the drag coefficient (commonly denoted as Cd, Cx or Cw) is a dimensionless quantity which is used to quantify the drag or resistance of an object in a fluid environment such as air or water. It is used in the drag equation...
cd = drag coefficient ρ = density of fluid (1.2 kg/m3 for air at NTP) v = flow velocity (m/s) A = characteristic frontal area of the body (m2) The drag coefficient is a function of several parameters like shape of the body, Reynolds Number for the flow, Froude number, Mach Numbe...
The measurements yield a relatively constant value of the drag coefficient starting from 2 diameters downstream of the sphere. At 7 diameters the measurement interval terminates due to the finite length of the duct. Error sources that need to be accounted for are the sphere support wake and ...
The injection of gas bubbles into a turbulent boundary layer of a liquid phase has multiple different impacts on the original flow structure. Frictional dr
Wind tunnel experiments were performed on both a life-like manikin and a human to find the aerodynamic drag of various body positions typical in sports. Information on aerodynamic drag is useful for modelling high speed sports. All the t... RA Walpert,CR Kyle - 《Journal of Biomechanics》 被...
The drag coefficient of a sphere changes as shown in Fig. 9.10.4 Within the range where Re is fairly high, Re = 1 × 103–2 × 105, the resistance is proportional to the square of velocity and CD is approximately 0.44 (subcritical region). As Re reaches 3 × 105 or so, like the...
