Analytical solutions for whirling groundwater flow in two‐dimensional heterogeneous anisotropic aquifers [PDF]
Water Resources Research, 2006 Analytical solutions are derived for steady state groundwater flow in a heterogeneous, anisotropic, semiconfined aquifer. The aquifer consists of a number of horizontal layers, while each layer consists of a number of homogeneous cells with different hydraulic conductivity tensors.

Theoretical Study of Fluid Forces on a Centrifugal Impeller Rotating and Whirling in a Volute [PDF]
, 1988 Fluid forces on a rotating and whirling centrifugal impeller in a volute are analyzed with the assumption of a two-dimensional rotational, inviscid flow. For simplicity, the flow is assumed to be perfectly guided by the impeller vanes.

Eccentricity Effects Upon the Flow Field Inside a Whirling Annular Seal [PDF]
Tribology Transactions, 1995 The flow field inside a whirling annular seal operating at a Reynolds number of 24,000 and a Taylor number of 6600 has been measured using a 3-D laser Doppler anemometer system. Two eccentricity ratios were considered, 0.10 and 0.50. The seal has a diameter of 164 mm, is 37.3 mm long, and has a clearance of 1.27 mm.
