TITLE: FLOW IN A ROTATING SEAL

BY: D R Glynn, FLOWSOLVE, London. Tel: +44 181 944 0940

DETAILS :

Streamlines

Reducing the annular gap between the shaft and housing causes the single recirculation to break up into 3 separate recirculation cells.

Streamlines with reduced angular gap

Reducing the annular gap further gives rise to a multiplicity of recirculation cells. This is of some importance, as these secondary flows can cause wear on the housing.

Streamlines with further gap reduction
