To evaluate an implosion dynamics with different equation-of-state (EOS) models in inertial confinement fusion (ICF), we compare two-dimensional radiation hydrodynamics simulation with QEOS, ideal gas EOS, and SESAME. The maximum density achieved during the implosion for the ideal gas EOS is higher than that for the QEOS. The sound velocity for the SESAME is faster than that for the QEOS. These results indicated that the EOS models affect the implosion dynamics in ICF.
