The formula for the pressure‐drag coefficient of a sphere which moves at extremely high speeds is derived. In the derivation it is assumed that the nose of the shock contour follows exactly the frontal half of the spherical surface and the local pressure on the frontal spherical surface corresp...
An argument on the drag coefficient of a sphere results in the expression C=C 0 [1+δ 0 /(R) 1/2 ] 2 where R is Reynolds number, C 0 δ 0 2 =24 , and δ 0 =9.06 This expression is in remarkable agreement with experiment for a wide range of R , i.e., 0≤R5000 .DOI...
Despite the abundance of experimental results on the free motion of solid, liquid, and gaseous particles under various conditions, there is no successful systematization of a drag curve across all three phases. Empirical models offered in the past can be quite useful within the limits of a par...
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 ...
Controlling microrobot locomotion in vessels and capillaries is crucial for precise drug delivery and minimally invasive surgeries. However, this is challenging due to the complex interactions with red blood cells (RBCs) and the difficulty navigating wit

Using boundary element anf finite-element methods, numerical results for the creeping motion of viscoelastic fluids past a sphere in the presence of a wall are presented. It is found that the fluid elasticity and the fluid shear-thinning can reduce the drag coefficient of the sphere remarkably. ...
It is well establised that dimples accelerate the drag-crisis on a sphere. The result of the early drag-crisis is a reduction of the drag coefficient by more than a factor of two when compared to a smooth sphere at the same Reynolds number. However, when the drag coefficients for smooth...
