Abstract We discuss the application of the numerical code TURMOIL to turbulent mixing in a simple spherical implosion, a much simplified version of an inertial confinement fusion implosion. Some form of Monotone integrated large eddy simulation is required to eliminate non‐physical oscillations, as shocks and contact discontinuities are present. The dissipation in the TURMOIL scheme is analysed. It is argued that this is relatively low and that the ‘sub‐grid’ dissipation can be precisely quantified. © British Crown Copyright 2007/MOD.
