Oseen's correction to stokes drag on axially symmetric arbitrary particle in transverse flow: A new approach
In this paper, Oseen’s correction to Stokes drag experienced by axially
symmetric particle placed in a uniform stream perpendicular to axis of
symmetry(i.e. transverse flow) is obtained. For this, the linear relationship
between axial and transverse Stokes drag is utilized to extend the Brenner’s
formula for axial flow to transverse flow. General expression of Oseen’s
correction to Stokes drag on axially symmetric particle placed in transverse
flow is found to be new. This general expression is applied to some known
axially symmetric bodies and obtained values of Oseen’s drag, up to first
order terms in Reynolds number ‘R’, are also claimed to be new and never
exist in the literature. Numerical values of Oseen drag are also evaluated
and their variations with respect to Reynolds number, eccentricity and
deformation parameter are depicted in figures and compared with some known
values. Some important applications are also highlighted
