AN EXPERIMENTER'S PERSPECTIVE ON VALIDATING CODES AND MODELS WITH EXPERIMENTS HAVING SHOCK-ACCELERATED FLUID INTERFACES

摘要

Predictive science in the US Stockpile Stewardship Program requires precision experiments and analyses to validate physics models and fluid simulation codes. In describing several science experiments used to validate applications of codes at Los Alamos National Laboratory, we offer an experimenter's perspective on this process within the context of the US Stockpile Stewardship Program. The validation of scientific code applications for simulating phenomena related to "weapons physics," the heart of the Stewardship Program, differs somewhat from traditional areas of physics.
