Abstract

Turbulence-induced vibration, particularly one generated by a fractal grid, has not been studied in much detail in the literature. This study focuses on the interaction of two side-by-side piezoelectric energy harvesters in fractal grid-generated turbulence. Three fractal grid patterns have been considered: “I”, square and cross. For each grid pattern, a full-factorial study of four important parameters has been considered: (i) Beam lengths and configurations, (ii) Mean flow velocity, (iii) Distance of the beams from the grids and (iv) the separation between the two beams. Experimental results show that all three fractal grids allowed for a significantly larger power output from the piezoelectric beams compared to a passive rectangular grid with a similar blockage ratio that was previously studied.
