Flow past an Impulsively Started Horizontal Cylinder in a Rotating Fluid

This paper presents an exact solution to the flow of a viscous incompressible fluid past an impulsively started horizontal cylinder in a rotating fluid. Dimensionless governing equations are solved by Laplace transform technique. Expressions of axial and transverse components of velocity, skin friction are derived using Laplace transform technique and effects of rotation parameter and time on these components are shown in graphs. It is demonstrated that the rotation leads to oscillatory motion solely due to rotation for smaller time, while the flow approaches steady state at larger time.
