摘要：

Fully developed forced convection through a variable-height shrouded fin array is studied numerically. Two different base thermal boundary conditions are considered being isothermal and isoflux heating. In either case, the shroud is assumed to be adiabatic. Following the application of two separate thermal energy equations, the conjugate heat transfer problem is solved. Different fin materials, spacings, heights, tip clearances, and sizes are examined. Considering these effects, pressure drop, heat transfer, and entropy generation aspect of the problem are studied in detail.
