Validation of a Hydrodynamic Code for Prediction of Mixing Instabilities

Bill Rider (XHM)


One of the most vexing challenges in hydrodynamics is the understanding and prediction of mixing. To understand these phenomena, there is no substitute for comparison between experiment and calculation, even in (or, perhaps, especially in) the era of ASCI. The results of these investigations are ameanable to visualization, whereby their fundamental nature can be interrogated through visual information. In cases where experiments allow for fine detail in space and time, a unique opportunity exists for in-depth evaluation of the physics. Just as experimentalists can learn much more from detailed information about the phenomena under examination, the comparison of such experimental data with calculation can provide a wonderful lens for understanding.
