Evaluation of the wind energy potential of two south west sites in Nigeria

Olaleye M. AMOO

Frontiers in Energy 2012, Volume 6, Issue 3,   Pages 237-246 doi: 10.1007/s11708-012-0201-2

Abstract: Wind resource assessment is a crucial first step in gauging the potential of a site to produce energy from wind turbines. In this paper, the wind energy potential of Abeokuta (07°03'N, 03°19'E) and Ijebu-Ode (06°47'N, 03°58'E), two south west sites in Nigeria were examined. Twenty years (1990–2010) of monthly mean wind data from a 10 m height were subjected to two-parameter Weibull analysis and other statistical analyses. The results show that the average annual mean wind speed variation for Abeokuta ranges from 2.2 to 5.0 m/s. For Ijebu-Ode, it ranges from 2.0 to 5.0 m/s. The wind power density variation based on the Weibull analysis ranges from 4.26 to 24.51 W/m for Abeokuta and from 8.54 to 76.46 W/m for Ijebu-Ode. Ijebu-Ode was found to be the better of the two sites in terms of annual variation of mean wind speed.

Engineering 2019, Volume 5, Issue 3,   Pages 576-579 doi: 10.1016/j.eng.2018.09.013

Abstract:

Flow transition from laminar to turbulent mode (and vice versa)—that is, the initiation of turbulenceEven for pipe flow, predicting the onset of turbulence requires sophisticated instrumentation and/or> against the local velocity changes with increasing velocity determines the onset of turbulence115%">γ and velocity (nonlinearity) can qualify the source of turbulenceThis understanding will have an impact on the future large-scale modeling of turbulence.
