ON THE VALIDATION OF THREE-DIMENSIONAL HYDRODYNAMIC MODELS FOR THE PENTLAND FIRTH REGION

Research output: Contribution to conferencePaperpeer-review

Abstract

A background knowledge of marine dynamics helps to prepare for the implementation of tidal turbines. The present paper investigates the hydrodynamic conditions within the Pentland Firth and Orkney Waters, which is home to some of the fastest tidal currents in the world. The data obtained from ADCP field measurement surveys are compared with numerical simulations developed using an open source finite element model-Telemac3D. Hydrodynamic modelling was carried out to study the sensitivity of the turbulence closure models for a period of 35 days, which are then calibrated and validated to find the optimal setting. Several configurations have been tested for both the horizontal and vertical turbulence scales, which highlighted the limitation of the constant viscosity and Smagorinsky models to appropriately resolve the eddies in the vertical scales. Nonetheless, substantial improvement was obtained for both models when coupled with the mixing length model for the vertical turbulence scale.
