Liquid Oxygen Post
S. E. Rogers, D. Kwak, U. Kaul, 1986

Liquid Oxygen (incompressible) flow across a flat plate with a cylindrical post rising perpendicular to the plate (and therefore the flow). The simulation is modeling a flow internal to a rocket engine. A Space Shuttle Launch Vehicle engine has a region in which many such posts obstruct flow of liquid oxygen to promote better mixing.

Visualization
post visualization

Interesting features of the flow are velocity changes just upstream of the post, and two counter-rotating vortices downstream of the post, where the greatest mixing occurs.

Since the fluid is incompressible, pressure is constant; visualizations of density or pressure are very boring.

Data Format
The data are in plot3d, single-zone, binary. All floating point data are in 32-bit IEEE format, SGI endian.
