TY - GEN A1 - Helling, Christiane A1 - Klein, Rupert A1 - Woitke, Peter A1 - Sedlmayr, Erwin T1 - Dust formation in brown dwarf atmospheres under conditions of driven turbulence N2 - Based on the knowledge gained from direct numerical simulations which are only possible in the microscale regime, a concept of driven turbulence is presented which allows to enter the mesoscopic scale regime. Here, dust formation under stochastic hydro- and thermodynamic conditions is studied: constructively superimposed stochastic waves initiate dust formation by the creation of singular nucleation events. It, hence, results a varying mean grain size and dust density in space and time. The newly formed dust changes the thermodynamic behavior from almost isotherm to adiabatic and chemically depletes the gas phase.
