This collection brings together five interrelated datasets from the University of Hull research program on the turbulent suspension of sediment in stratified shear flows. It includes: numerical simulations of thermally stratified and sediment-laden channel flows performed using open-source NEK5000 v19, with initial conditions and post processed data; experimental measurements from a novel Stratified Flow Facility (SFF), with raw and processed (insitu) ultrasonic and optical equipment; and a full brief of facility design. The collection also links to a GitHub repository containing a Python-based processing suite for stratified flow simulations and experiments. Together, these datasets provide raw and processed data, experimental metadata, and technical documentation to support the study of turbulence, internal waves, particle transport, and measurement methodologies in stratified fluid dynamics.
