# Title: The equation of state of a partly homogenized plasma of low-dense porous matter

Abstract: The equation of state (EOS) of a low-density porous substance plasma is proposed in the form of continuous media EOS containing, as a pressure control parameter, the degree of plasma homogenization, which is function of the initial porous structure, as well as of the current values of plasma density and temperature. Using the partially-homogenized-plasma EOS an approximate analytical solution is found and numerical calculations were performed of the problem of thermal expansion of a flat layer of porous matter. The features of the obtained results are discussed in comparison with the case of a continuous substance of equivalent chemical composition. The proposed equation of state is used to analyze the experimental data on porous substance heating with laser and X-ray pulses.
