WebApr 13, 2024 · Flow field reconfiguration and drag reduction have been investigated by numerically solving Navier-Stokes equations, with the 2nd order dispersion controlled dissipative scheme adopted for the convective term discretion and the 2nd order central difference scheme for viscous term. Spikes and sideward jets nearby the spike noses … In such situations, the airfoil is stalled and has higher pressure drag than friction drag. In this case, the body is described as a blunt body. A streamlined body looks like a fish , Oropesa, etc. or an airfoil with small angle of attack, whereas a blunt body looks like a brick, a cylinder or an airfoil with high angle of attack. … 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 … See more Concept The force between a fluid and a body, when there is relative motion, can only be transmitted by normal pressure and tangential friction stresses.
