    Biomass energy is becoming a promising option to reduce CO2 emissions, due to its renewability and carbon neutrality. Normally, biomass has high moisture and volatile contents, and thus its combustion behaviour is ...
  • Scale effects in testing of a monopile support structure submerged in tidal currents. 

    Okorie, Oghenevwori Patricia (Robert Gordon University School of Engineering, 2011-11)
    Climate change and energy security are key issues motivating the development of Tidal Current Energy (TCE) technology. Small scale model testing of TCE devices is a major challenge facing the technology due to turbulent ...
