Although these papers are earlier than what we would normally keep on the web, they have been retained because they are the basic for comparisons to the parallel computation efforts. The computations have taken much longer than anticipated.

The opposed jet flow system offers some unique characteristics that can be used for validation of DNS/LES simulations. Two laminar jets interact in the central region of a large cylinder. The jets are laminar; thus, cyclic boundary conditions are not needed. The only constraints come from the initial conditions, which can be inputted from experimental measurements.
