文摘
- •
Shear-thinning fluids promote heat transfer.
- •
Entrance length increases with the extent of shear-thinning.
- •
Nusselt number for a semicircular duct is higher than that for a tube.
- •
Yield stress lowers the entrance length.
- •
Limiting Nusselt number values for ducts of several shapes are presented.
