Abstract

Hydrodynamic instabilities, the most significant of which is Rayleigh-Taylor instability (RTI), play a significant role in many physical phenomena. So how to decrease the growth rate of these instabilities is an important purpose in ICF fuel targets. In this research, reducing the growth rate of RTI for various fusion fuel targets has been investigated in two stages: First, it is indicated that applying different nanostructured porous linings at the ablation front of them in the absence of a strong magnetic field causes to decrease RTI growth rate and second, it is shown that using various nanostructured porous linings at the ablation front of these targets accompanying magnetic field exerting to the ablative surface of them, leads to more reduction of RTI growth rate. In both of these two phases, RTI growth rate is acquired analytically using conservation equations, boundary conditions and approximate methods and it is indicated that applying nanostructured porous linings and exerting a powerful magnetic field, will decrease RTI growth rate.
