AB: A total of approximately 120 papers containing original multifluid intermediate-scale experiments were reviewed. Depending on the main focus of the experiments, the papers were divided in the following categories: 1) Flow and transport, 2) Dissolution, 3) Imaging, 4) Quantification and Characterization, and 5) Enhanced Remediation of NAPL source zones. Intermediate-scale experiments are conducted to obtain on understanding of flow and transport phenomena at a larger scale, to test and verify remediation techniques, and to provide data sets for testing of numerical models. Both column studies as well as flow cell experiments without NAPL in the porous media were not considered. The earlier experimental work, starting with the work by Schwille (1988), primarily focused on nonaqueous phase liquid (NAPL) flow phenomena and NAPL dissolution. More recently, the emphasis is mostly on enhanced remediation using techniques such as alcohol flooding, alcohol flushing, and steam injection. In this presentation, the major contributions of the reviewed experiments as well as recommendations for future flow cell research will be presented.
