Master-mode set for 3D turbulent channel flow

Abstract

Master-mode set of the turbulent channel flow is calculated and stored in a database available online. The master-mode set is a subset of the modes used in direct numerical simulation. While being much smaller than the set of modes needed for fully resolved DNS the master-mode set contains full information about the developed turbulent flow. Master-mode set may be used directly as an approximate representation of the flow, while the remaining modes can be recovered with an additional calculation. The online database allows a remote user to upload a Fortran code for data analysis, compile and run it on the server with a direct access to the database.
