plunger velocity = 80 cm/sec, aluminum, acceleration time = 0.1 sec
2. Surface tension = 670 dyne/cm
3. Surface
tension = 3000 dyne/cm
The first simulation shows the flow pattern without surface
tension
and the others show the effect of surface tension. Two
values of surface tension are used for flow simulations
In the second one, 670 dyne/cm is used, because this
value represent the surface tension of Al in a reducing gas environment,
and In the last one, 3000 dyne/cm, because this value represents the surface
tension of Al when an oxide layer gets formed on the surface.
As surface tension value increases, the wave created
tend to come down to reduce the surface area.
