Numerical Simulation of a Randomly Heated, Thermally Unstable Fluid.

Abstract

Numerical simulations examine the response of a radiation driven thermally unstable fluid medium to randomization of the heating rate. Condensed structures develop more quickly as the heating becomes more spatially and temporally variable. Furthermore, the duration and intensity of the radiation events are altered. An analysis is presented which indicates that increasing the amplitude of temperature perturbations will lead to increases in radiated energy output. Keywords: Instability; Condensation; Solar Corona.
