Abstract The interaction between a flow and flexible structure can provide fascinating insight into the vortex shedding phenomenon any propagation mixing characteristics, which relate to plethora of applications such as heat transfer, snoring, musical instruments, or propulsion mechanisms. In this investigation, influence confinement on flapping behaviour flag is explored. particular, hysteresi...

Abstract This study aimed to investigate the influence of processing parameters on mechanical properties auxetic polyurethane foams including Poisson’s ratio and Young’s modulus. 12 different scenarios were considered using method Plackett–Burman in design experiments with three replicates for each one. Eventually, 36 prepared densities initial thicknesses, heating temperatures times, applied c...
