Drag on an elliptic cylinder in a fluid particle suspension

Abstract

Several researchers over years have studied the oscillatory flow problems concerning various classes of fluids. Kanwal [1, 2] has studied analytically the oscillations of symmetric bodies like circular cylinder, sphere, spheroid and elliptic cylinder in classical viscous liquids. Frater [3, 4] has examined the oscil- lations of a sphere and a circular cylinder in a viscoelastic fluid of Oldroyd's-B type and studied numerically the effects of the viscoelastic and frequency parameters on the drag experienced by the bodies. S. K. Lakshman Rao et al. [5, 6, 7, 8, 9] have examined the harmonic oscillations of a circular cylinder, sphere, spheroid as well as an elliptic cylinder in micropolar and couple stress fluids. Kumar [10] has discussed the oscillations of a circular cylinder and a sphere in a fluid-particle suspension and studied the effects on the drag experi- enced by the bodies with reference to the geometric and fluid characteristic parameters.
