| Abstract
| - A detailed analysis has been performed for a heterogeneous photocatalytic Taylor vortex reactorthat uses flow instability to recirculate fluid continually from the vicinity of the rotating innercylindrical surface to the stationary outer cylindrical surface of an annulus. In the presentresearch, a detailed time-accurate computation shows the different stages of flow evolution andthe effects of the finite length of the reactor in creating eddies, which results in a very highoverall efficiency of photocatalytic conversion. The physical arrangement considered is such thatpollutant degradation is maximized by the motion of fluid particles in a specific regime ofcentrifugal instability. Also provided are detailed flow structures for the chosen parameterswhen the reactor is started impulsively.
