The effects of atomic-level mixing are systemically investigated in a multifluid interpenetration mix model,and results are compared with the single-fluid model’s simulations and experimental data.It is shown that increasing themodel free parameter α,shock Mach number,and the initial density discontinuity makes the mix length and fraction ofmixing particle increase,resulting in the lower shock temperatures compared with the results of single-fluid model withoutmixing.Recent high-compressibility direct-drive spherical implosions on OMEGA are simulated by the interpenetrationmix model.The calculations with atomic mixing between fuel and shell match quite well with the observations.Withoutconsidering any mixing,the calculated neutron yields and ion temperatures are overpredicted;while inclusion of theinterpenetration mix model with the adjustable parameter α could fit the simulated neutron yields and ion temperatureswell with experimental data.
