Mathematics deals with pure numbers: 1, 2, 3; fractions; and more exotic numbers such as pi. Since pi depends on lengths, we might think its value depends on our units. But it is the ratio of the ...

Self-organization of moving objects in hydrodynamic environments has recently attracted considerable attention in connection to natural phenomena and living systems. However, the underlying physical ...

A body moving through a fluid experiences a drag force, which is usually divided into two components: frictional drag, and pressure drag. Frictional drag comes from friction between the fluid and the ...

The HyperBLaF is a Mach 8 blowdown wind tunnel used for fundamental studies of compressible turbulence, shock wave/boundary layer interactions, shock/shock interactions and configuration studies of ...
