The project "Experimental investigation of flow fields in the interstices of bulk particles using optical measurement techniques" examines the flow field in granular assemblies (reference configuration). The main emphasis in funding period 2 (FP2) will be on extending the method to quantities other than velocity, such as temperature and gas dispersion measurements. In cooperation with another project, simultaneous measurements of gas temperature and velocity will be set up by using thermographic phosphor tracer particles for the measurements. Further, laser-induced fluorescence (LIF) of anisole will be used for the determination of gas dispersion in the packed bed. The bed particles will be changed to more challenging and relevant polyhedral particles. The project delivers spatially and temporally resolved validation data for the other numerical projects.
