This paper describes an experimental study of the drag force experienced by a stationary smooth sphere placed in a boundary layer type gradient flow. The test sphere was kept close to as well as away from the boundary. Both smooth and rough boundary conditions were studied. The Reynolds number...

Therefore, the drag coefficient of a sphere with dimples becomes smaller than that of a smooth sphere. Then, the critical Reynolds number shifts to lower Reynolds number side as the depth of dimple becomes deeper. However, the ... K Aoki,K Muto,H Okanaga - 《Nihon Kikai Gakkai Ronbunshu...
A mechanical model dependent on the force balance of settling particles was adopted, and the experimental data were analyzed in detail. A model for predicting the drag coefficient of spherical particles in the power-law fluids was established. On this basis, a two-dimensional shape description ...

Surface condition – smooth, variable by design, damaged by wear, corroded • Finish on rope fibre – most reduce friction but coatings on HMPE ropes are intended to increase it. • Pressure against a surface – a function of the tension, the surface radius and any tendency for the rope...
A study on the temperature dependent drag coefficient on a sphere in flowing helium II.The drag coefficient on the surface of a sphere for temperatures between 1.6 K and 2.1 K has been measured in flowing He II. The measurement suggests a temperature dependence to the drag coefficient not ...
from experimental measurements of the single particle terminal settling velocity, the corresponding drag coefficient was found to be larger than that of a smooth, rigid sphere whereas to be in agreement with that of a elastic sphere. in... 黄晓波,王建政,张英,... - 《中国科学院大连化学物理...
In the latter case, it was found that the early crisis of drag for the sphere is accompanied by a crisis of its heat exchange with gas. In addition, the numerical simulation of the heat exchange of a drop of liquid with a gas stream was carried out without taking into account its ...
