The co-rotating disks system is applied to a wide range of industrial machinery. This study focuses on co-rotating disks of magnetic disk storage devices. Although numerous experimental and numerical studies have been given to the relevant flow field, the flow physics has not been completely elucidated as a result of its inherent complexity. Consequently, investigating the flow field in detail is required. Many studies have analyzed this flow type; however, for the sake of brevity, only the most relevant works are cited in this work.
