The vortex-based dimple heat transfer enhancement was introduced as a new heat transfer enhancement and cooling technique.The major characteristics include high heat transfer coefficients

low friction factors and high overall thermal performances.After review of research work on heat transfer enhancement with dimple in the last decade

the heat transfer behavior

flow resistance and vortex structures of dimpled surface were presented

and the influence of parameters

such as dimple shape

depth

and Reynolds number

were also discussed. While the thermal performances of dimples in rotating channel

circular tube and impingement target surface were described and compared with that of trip-strip

this paper provides a visibility into the dimpled surface

which is a new and potential heat transfer enhancement technology with wide applications.
