On the degradation of hot spot performance due to mid-to-high-mode hydrodynamic instabilities
Dongxue Liu, Jiaqin Dong, Yunxing Liu +5
In an ignited design of inertial confinement fusion, the role of mid-to-high-mode hydrodynamic instabilities in degrading hot-spot performance, beyond reducing temperature, remains…
A theoretical model for quantifying the imprinting sensitivity of direct-drive inertial confinement fusion implosions
Dongxue Liu, Jiaqin Dong, Yunxing Liu +5
To quantify the sensitivity of diverse implosion designs to laser imprinting, we developed an equivalent perturbation model that maps laser imprinting as the initial target surface…
A buoyancy-drag model with a time-varying drag coefficient for evaluating bubble front penetration depth
Dongxue Liu, Tao Tao, Jun Li +3
To evaluate and control bubble front penetration depth induced by ablative Rayleigh-Taylor instability (ARTI) from a weakly nonlinear phase to a self-similar phase, we…
A one-dimensional mixing model for the impact of ablative Rayleigh-Taylor instability on compression dynamics
Dongxue Liu, Tao Tao, Jun Li +3
A one-dimensional mixing model, incorporating the effects of laser ablation and initial perturbations, is developed to study the influence of ablative Rayleigh-Taylor instability o…
