In microflows where Reynolds number is much smaller than unity, screwing motion of spirals is an effective mechanism
of actuation as proven by microorganisms which propel themselves with the rotation of their helical tails. The main focus
of this study is to analyze the flow enabled by means of a rotating spiral inside a rectangular channel, and to identify
effects of parameters that control the flow, namely, the frequency and amplitude of rotations and the axial span between
the helical rounds, which is the wavelength. The time-dependent three-dimensional flow is modeled by Stokes equation
subject to continuity in a time-dependent deforming domain due to the rotation of the spiral. Parametric results are
compared with asymptotic results presented in literature to describe the flagellar motion of microorganisms.
