  2. Drag (physics) - Wikipedia

    en.wikipedia.org/wiki/Drag_(physics)

    In supersonic flow regimes, wave drag is commonly separated into two components, supersonic lift-dependent wave drag and supersonic volume-dependent wave drag. The closed form solution for the minimum wave drag of a body of revolution with a fixed length was found by Sears and Haack, and is known as the Sears-Haack Distribution .

  3. Coulomb drag - Wikipedia

    en.wikipedia.org/wiki/Coulomb_drag

    The phenomenon considers two spatially isolated layers. In between the two layers, there can be vacuum or an insulator. When an electric direct current is driven in the active layer, it drags carriers in the passive layer due to Coulomb interaction, this charge imbalance leads to a drag voltage V D induced in the passive layer.

  4. Drag coefficient - Wikipedia

    en.wikipedia.org/wiki/Drag_coefficient

    Drag coefficients in fluids with Reynolds number approximately 10 4 [1] [2] Shapes are depicted with the same projected frontal area. In fluid dynamics, the drag coefficient (commonly denoted as: , or ) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water.

  5. Drag equation - Wikipedia

    en.wikipedia.org/wiki/Drag_equation

    is the drag coefficient – a dimensionless coefficient related to the object's geometry and taking into account both skin friction and form drag. If the fluid is a liquid, c d {\displaystyle c_{\rm {d}}} depends on the Reynolds number ; if the fluid is a gas, c d {\displaystyle c_{\rm {d}}} depends on both the Reynolds number and the Mach number .

    Creeping flow past a falling sphere in a fluid (e.g., a droplet of fog falling through the air): streamlines, drag force F d and force by gravity F g. At terminal (or settling) velocity , the excess force F e due to the difference between the weight and buoyancy of the sphere (both caused by gravity [ 7 ] ) is given by:
