The flow of gas into and out of galaxies regulates their evolution over cosmic time. The dynamics of these multiphase flows are sensitive to the small scale processes that mediate the mixing of the hot and cold phases. I will highlight examples where this is mixing is acutely important, such as, galactic wind launching and circumgalactic medium dynamics, as well as in seemingly unrelated phenomena like rocket engines and clouds in Earth’s atmosphere. Then, based on a suite of high resolution simulations, I will present a new model founded on the fractal nature of radiative turbulent mixing layers that can fully characterize the physical processes that control the multiphase mixing.
