Study of low-order numerical effects in the two-dimensional cloud-top mixing layer

Eckhard Dietze Juan Pedro Mellado Bjorn Stevens Heiko Schmidt Large-eddy simulation (LES) has been extensively used as a tool to understand how various processes contribute to the dynamics of the

Two-fluid formulation of the cloud-top mixing layer for direct numerical simulation

A mixture fraction formulation to perform direct numerical simulations of a disperse and dilute two-phase system consisting of water liquid and vapor in air in local thermodynamic equilibrium using a two-fluid model is derived and discussed. The goal is to understand the assumptions intrinsic to this simplified but commonly employed approach for the study of two-layer buoyancy ...
