Identification of the velocity and the concentration field with PIV/LIF measurements above a structured permeable seabed
In the context of the DFG research training Group Baltic Transcoast the scalar transport of discharged submarine groundwater and the included matter will be investigated. The focus of the research is the mixing of such particles under the influence of the waves in the shallow coastal water. The investigation will take place in the water channel of the chair of Fluid mechanics. The waves will be generated by a Piston type wave generator and can be varied with respect to the specific wave parameters. In the water channel a permeable ground model is installed which allows the intrusion of a florescent tracer fluid into the measurement area. The transport of this tracer in the water column is affected by the wave motion and will be analyzed using the current optical measurement technology present. The methods used are on the one hand the classical Particle Image Velocimetry, to determine the velocity field in the measurement area. On the other hand, simultaneously the Laser Induced Florescence technique will be used to obtain the concentration field. Thus the connection between the unsteady velocity field and the mixing of tracers can be determined quantitatively.
