TLDR
It is observed that the uncertainty in the turbine's rotation is more influential on the power output compared to free-stream velocity, and the sensitivity of the turbine’s performance to these input uncertainties is quantified using probability methods, including response surface, PDF and CDF.

Experimental analysis of the flow field around horizontal axis tidal turbines by use of scale mesh disk rotor simulators

TL;DR: In this article, the authors identify and provide an understanding of the principal parameters that govern the downstream wake structure and its recovery to the free-stream velocity profile, and demonstrate that there are a number of interdependent variables that affect the rate of wake recovery and will have a significant impact on the spacing of marine current turbines within an array.

Blockage corrections in wind tunnel tests of small horizontal-axis wind turbines

TL;DR: In this paper, the effects of tunnel blockage on the turbine power coefficient in wind tunnel tests of small horizontal-axis wind turbines were quantitatively investigated by measuring the tunnel velocities with and without rotors using a pitot-static tube under various test conditions.
