A comparison between ducted turbine theory and inviscid simulation

Abstract

This paper describes the use of an inviscid approach to model a ducted turbine and a comparison of simulation results with a particular one-dimensional theory. The aim of the investigation was to gain a better understanding of the ideal diffuser, a concept that is developed in the theory. An optimisation of duct shape and a set of simulations with a varied group of shapes showed that duct length, inlet radius and outlet radius are not sufficient to define an ideal diffuser. A set of simulations with cylindrical ducts confirmed the theory that a duct optimised for one loading is less than ideal at other loadings.

A novel aerodynamic controllable roof for improving performance of INVELOX wind delivery system

“…Many researchers and innovators have developed new technologies related to the wind energy (Al-Bahadly and Peterse, 2011;Chenniappan and Balakrishnan, 2017;Lin and Hong, 2010;Shen et al, 2011). Different types of single and multiple arrays of ducted turbines have been developed so far (Frankovic´and Vrsalovic´, 2001;Georgalas et al, 1991;McLaren-Gow et al, 2013). Single-ducted turbines have been proved to be effective and promising for small wind applications.…”
