Abstract

The pressure drops of laminar developing and developed flow in annular-sector ducts with small round corner have been investigated experimentally. Numerical simulation has been performed to study the effect of the small round corner on the friction factor in the developed region. It has been found that with the increase in corner radius, the value of f Re decreases. In the range of r_c/r_ofrom 0.031 to 0.12, the decrease in f Re varies from 0.048% to 0.1% for the five apex angle computed.
