Experimental study of the effect of fitting winglets to a tidal turbine

Experimental study of the effect of fitting winglets to a tidal turbine

The projects aim is to study the effect of adding winglets to a 1/20th scaled tidal turbine, and measure their impact on the Power and Thrust coefficients (CP and CT). In theory, an increase in the CP would be a result of the reduction of any tip losses. Previous CFD simulations and experiments carried out on wind turbines suggest that a winglet facing the suction side with a height of around 4% and a 25% radius would be optimal for this purpose.

Site suitability analysis for renewable off-grid systems using GIS-MADM in Sudan

Site suitability analysis for renewable off-grid systems using GIS-MADM in Sudan

This research aims to investigate the potential for implementing clean off-grid energy systems for rural electrification in Sudan. Analysis using the GIS (Geographic Information System) -MADM (Multiple Attribute Decision Making) method will identify sites suitability for renewable off-grid electricity systems. The methodology includes four main strands of work: (a) assessment of renewable energy availability in Sudan, (b) identifying suitable weighting criteria for site selection, (c) location of appropriate sites that fulfil the criteria via MADM-GIS, and (d) performing experts’ NGT (Nominal Group Technique) via AHP (analytic hierarchy process) – SAW (simple additive weighting) to select the most suitable sites in rural Sudan.

Transitioning Bangladesh to renewable power

Transitioning Bangladesh to renewable power

This research analyses the policies required to guide Bangladesh through its sustainable energy infrastructure transformation to support its aspiration of becoming a developed country by 2041. Based on the model outcomes, the research will suggest what renewable share in the energy mix should be progressively elevated in accordance with the future escalation in financial affordability and technical advancement of the overall efficiency of suitable renewable systems for the country.
