Abstract: 

The nanofluid flow in a curved channel formed by two concentric cylindrical surfaces is studied. The flow is caused by a constant azimuthal pressure gradient. The hydrodynamic and thermal characteristics of the flow are investigated. The influence of various factors on the centrifugal instability is studied as well.

Keywords: centrifugal instability, curvilinear channel, heat-mass transfer, nanofluid
