Abstract |
Wind energy is one of the most general natural resources in the world. However, as of today, generating electricity out of wind energy is only available from big wind generator, Furthermore, an axial-flow turbine is the only way to produce electricity in the big wind generator. This paper is for the guidance of drawing impact fact about power turbine using cross-flow type transferring wind energy to electricity energy. It will find the ideal value which enables to make cross-flow power turbine(CPT) using computational fluid dynamics(CFD) code. This study tries to analyze the “Solidity” characteristics. We can find out turbine-blade number through CFD. CFD is using “Fluent_ver 6.3.16”, and the data from its result will judge fan-blade performance through specific torque and specific power from each “Solidity” model. Based upon the above, we will make cross-flow power turbine of multi-blade centrifugal fan instead of axial-flow type. |
