Due to the high consumption of energy in recent years and global efforts replace fossil fuels with clean energy, need for high-efficiency renewable systems has become necessary. Small VAWTs are suitable candidates production, due their advantages over other power systems; nevertheless, aerodynamic performance is modest. This paper attempts improve Darrieus VAWT by examining turbine design param...

Darrieus–Landau (D-L) instability can cause significant acceleration in freely expanding spherical flames, which lead to accidental large-scale gas explosions. To evaluate the potential of using high-pressure lab-scale experiments predict onset cellular instabilities atmospheric explosions, experimental measurements for hydrogen and methane mixtures are conducted, laboratory explosions at eleva...
