Study of Oscillatory Flow in Curved Channel

Abstract

Oscillatory laminar flows in curved pipes were numerically analyzed and studied experimentally. Flow regimes were classified into seven patterns according to the Dean number De and the Wormersley number α. For large De and α flow pattern was found to change abruptly across a certain boundary. The phase lag of the pressure in De. The friction factors also increased with α, but increased with De following a slight decrease.
