Actuator disc is one of the simplest model used in simulating the presence of tidal devices. In recent years, three-dimensional RANS models have been employed in simulating the wake effects behind the actuator disc. Nonetheless, majority of these works were conducted on an extremely small scale domain, in which some of the parameters utilised were unsuitable to be replicated for a large scale study. Thus the purpose of this paper is to discuss the experience learnt from modelling a 20-meter diameter turbine via the actuator disc approach for a simple channel, previously undertaken by the authors. Crucial dissimilarities between the small and large scale models are highlighted. Further, several foreseeable challenges in implementing the actuator disc for an ocean circulation model are also underlined. It is hoped that the present paper could benefit other researchers who are transitioning from a very small actuator disc model to simulating a realistic turbine dimension for a regional scale application.
