Over the past years, electrical energy demand has increased dramatically worldwide. Malaysia being a developing country, the need for electrical energy is expected to rise yearly. Therefore, to prevent the energy crisis and global warming, the Malaysian Government has started to switch focus to renewable energy technologies. This paper will analyse the wake characteristics produced by the vertical axis tidal turbine design. Malaysian waters have shallow depth and low water current speed, contributing to an ideal solution to implement a nested turbine. The numerical analysis compares the wake generated from the actual turbine design and a hypothetical ‘actuator’ cylinder which represents vertical axis tidal turbine. The simulation result has been validated with other studies which brings about the understanding of the wake generated from nested turbine and ‘actuator’ cylinder.
