Theoretical models capable of describing the performance of wind turbine arrays can be used to explore a wide range of parameters and to guide the design of more expensive and detailed numerical experiments. However their validity under realistic atmospheric conditions must first be established. In this study we aim to test one such theoretical model (Nishino, 2016, henceforth N16) under realistic forcing conditions, to attempt to identify the circumstances under which it succeeds, and also…

Two-scale momentum theory for very large wind farms

A new theoretical approach is proposed to predict a practical upper limit to the efficiency of a very large wind farm. The new theory suggests that the efficiency of ideal turbines in an ideal very…

In situ data analytics for highly scalable cloud modelling on Cray machines

This paper presents the analytics approach of MONC, where cores of a node are shared between computation and data analytics, and describes the IO server framework and analytics workflow, which is highly asynchronous.

FARM EFFICIENCY OF LARGE WIND FARMS: EVALUATION USING LARGE EDDY SIMULATION

Large eddy simulation study of fully developed wind-turbine array boundary layers

It is well known that when wind turbines are deployed in large arrays, their efficiency decreases due to complex interactions among themselves and with the atmospheric boundary layer (ABL). For wind…
