DOI: 10.1016/j.oceaneng.2019.106293
Abstract: Abstract A way to quantified diffuser-rotor interaction is presented for a micro-diffuser-augmented hydrokinetic turbine (MDAHT) base on the actuator disc theory (Jamieson, 2011). The large eddy simulation/Reynolds-averaged Navier–Stokes model (DES) for computational fluid dynamics were… read more here.

DOI: 10.1016/j.renene.2020.11.059
Abstract: Abstract Placing a diffuser around a wind turbine can increase its power output, but not all mechanisms by which the diffuser alters the aerodynamics have been investigated thoroughly. Here, we concentrate on one such mechanism:… read more here.
