Untangling the Mysteries of Turbulence: A Data-Driven Visualization Study of Active Flow Control in Channel and Pipe Flows Using Numerical Simulations

This is the first bibliometric study of its kind in this domain and it investigates the use of numerical simulations for research related to turbulent drag reduction in channel and pipe flows using active flow control techniques using data from two databases: Scopus and Web of Science (WOS). A bibliometric analysis of 603 research publications related to active drag reduction using numerical simulations for turbulent channel and pipe flows has been done to analyze the progress in this research domain since the year 1984. The publications have increased significantly in this domain since 2017, one of the biggest reasons for this can be the increased availability of computational resources. Maximum work in this domain has been done by developed nations such as China, USA, UK, and Japan etc. The research can be categorized into four major clusters. The first cluster focuses on research exploring types of active drag reduction methods/agents used and the mechanisms involved. The second cluster involves different types of numerical modelling techniques used for flow control and their analysis. The third and fourth cluster highlights the different types of geometrical configurations used for numerical simulations and their impact on drag reduction and heat transfer related themes respectively.
