Simulation of wind turbine wake interaction using the vorticity transport model [PDF]
, 2010 The aerodynamic interactions that can occur within a wind farm can result in the constituent turbines generating a lower power output than would be possible if each of the turbines were operated in isolation.

Time and space optimality of rotor-router graph exploration [PDF]
Information Processing Letters, 2017 We consider the problem of exploration of an anonymous, port-labeled, undirected graph with $n$ nodes and $m$ edges and diameter $D$, by a single mobile agent. Initially the agent does not know the graph topology nor any of the global parameters. Moreover, the agent does not know the incoming port when entering to a vertex.

Rotor wake interactions with an obstacle on the ground [PDF]
, 2018 An investigation of the flow around an obstacle positioned within the wake of a rotor is described. A flow visualisation survey was performed using a smoke wand and particle image velocimetry, and surface pressure measurements on the obstacle were taken.

Experimental investigation on ducted counter-rotating axial flow fans [PDF]
, 2011 An experimental study on counter-rotating axial-flow fans was carried out. The fans of diameter D = 375 mm were designed using an inverse method. The counter-rotating fans operate in a ducted-flow configuration and the overall performances are measured ...
