Non‐linear transient phenomena in a complex recirculating flow: A numerical investigation

A role of numerical methods in engineering research is illustrated in the present work, namely the use of computer algorithms as experimental facilities. A complex recirculating flow in a three‐dimensional cavity was simulated and an extensive data base was generated which complements data measured in concurrent physical experiments. The objective of this numerical investigation was to improve understanding of physical phenomena in recirculating flows. The dominant physical phenomena in this shear‐driven flow simulation are Taylor‐Görtler vortices. These structures are intimately coupled with the primary recirculating flow and the effects of end‐wall viscous damping.
