Abstract: We report broadband acoustic converging and asymmetric converging based on mono- and dual-layer thermoacoustic phased arrays of Bessel-like beams, respectively. Based on the thermoacoustic units, we design a converging lens constructed by a monolayer phased… read more here.

Abstract: We examine the turbulent boundary layers developing over convergent-divergent riblets (C-D riblets) with three different heights (h+ = 8, 14, and 20) at Reθ = 723 using particle image velocimetry. It is observed that although… read more here.
