The drag coefficient (non-dimensional drag) is equal to the drag force divided by the product of velocity pressure and frontal area. The velocity may be that of the object through the air (or any other gas) or the air velocity past a stationary object.

AERODYNAMIC DRAG ON VARIOUS OBJECTS . In this lesson, we will: • Look at tables of drag coefficient for various objects (geometric shapes, parachutes, trees, people, buildings, etc.) • Do a “student-friendly” example problem – drag on a bicycle . Drag Coefficients on Objects of Various Shapes . See tables in the textbook, copied here.

2022年12月15日 · The experiments focus on drag force evolution and the associated flow structures to predict the drag regimes across the range of inclinations considered. Measurements show that drag increases rapidly with inclination for small angles, while at high angles it being nearly independent of inclination.

The drag coefficient quantifies the drag or resistance of an object in a fluid environment. Any object moving through a fluid experiences drag - the net force in the direction of flow due to pressure and shear stress forces on the surface of the object.

2019年1月1日 · This paper presents a study of the terminal fall velocity, drag coefficient and descent style of ‘wavy-edge’ flat particles. Being highly non-spherical and with a size of up to a few centimetres, these particles show strong self-induced motions that lead to various falling styles that result in distinct drag coefficients.
