The collapse of turbulent fluid, apart from being interesting for its own sake, is also of interest to the supernova problem; a failed ignition can cause a turbulent re-collapse, which might lead to a subsequent reignition under more favourable circumstances. We use the FLASH code, developed at the Center on Astrophysical Thermonuclear Flashes, to run small-scale DNS of the evolution of a compressible, combustible turbulent fluid under the effect of a forced radial homogeneous compression. We follow the evolution of density and temperature fluctuations over the compression history. This work is supported by the Department of Energy under Grant No. B341495 to the Center for Astrophysical Thermonuclear Flashes at the University of Chicago.
