In this study, a moderately flexible rotor is investigated experimentally in water channel. The consists of single blade with simplified rectangular geometry and tested various pitch angles at different rotational speeds. flapwise bending deformation induced torsion the are measured using image processing tools, flow fields extracted Particle Image Velocimetry. behaviour depends strongly on ang...

Supercapacitors are popular due to their higher power density than that of batteries, and widely used in electronics. It bridges the gap between electrolytic capacitors rechargeable batteries. Electrochemical pseudocapacitors use metal oxides or conducting polymers. The graphene oxide/polyaniline (GO/PANI) composite, as a supercapacitor electrode material was prepared increase energy storage ef...
