dc.description.abstracteng	This study deals with the modeling of a laboratory experiment where steady states as well as transients of double diffusive staircases can be observed by Particle Image Velocimetry (PIV) in a fluid layer. A stabilizing temperature gradient and a destabilizing gradient of ion concentration are established in a thermal and electrochemical system. The system can be described by the dimensionless thermal and chemical Rayleigh numbers Ra_T and Ra_c to form a 2D parameter space. The experimental result of this study leads to identify borders of staircase formation within this 2D parameter space and leads to a deeper understanding of the formation process of thermohaline fingers and staircaises. An advantage of the experimental setup is the possibility of adding rotation to study the influence of Coriolis forces on finger convection and staircaise formation.	de
