Interactive investigation of an industrial case-study is addressed, through the utilisation of multimedia presentation technology. A principal aim is to evaluate results through interactive interrogation, covering industrial requirements to identify optimal operating windows through parameter adjustment. Both steady and transient simulated flow-states are evaluated. The data is interpreted, utilising the MMS to navigate through the large data-set involved. Flow settings and results are discussed, whilst innovative presentation techniques are described and implemented through multimedia environments. World-wide-web delivery, streaming, underlying graphs, data-compression, voiceover and availability of cruise-control navigation, are multimedia-related features that can render the current system accessible to wide audiences over the internet. The generality of presentation methods classifies this case-study as a characteristic example, to be adopted for alternative data-sets.
