Free-Stream Flow Past a Solid Sphere

* Comparing free-stream flow over a past sphere at Reynolds number of a)Re=25, b)Re=50, c)Re=100, d)Re=150, e)Re=200

* As the Re number increases, a circulation flow is formed in the wake region

Free-Stream Flow over a sphere:

YSZ Drop Impact at High Impact Velocity

* The droplet size is 50 micron, and solid core size is 25 micron
* The impact veloicty is increased to V=250 m/s
* The high impact velocity causes the 'swirling' fluid motion
* The fluid 'splashes' at high impact velocity
