Numerical investigation of processes in the lignite-fired furnace when simple gray gas and weighted sum of gray gases models are used
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
Comparison of the numerical investigation results was carried out when the simple gray gas (SGG) and weighted sum of gray gases (WSGG) models are used to model the radiative properties of the gas phase inside the lignite ...
The applicability of construction and demolition waste components for radionuclide sorption
(Elsevier Sci Ltd, Oxford, 2018)
Following the guiding "3R" principle of sustainable development (Reduce, Reuse and Recycle), the potential applicability concerning various components of construction and demolition waste (C&DW) was investigated for ...
Wind energy resource development in Ethiopia as an alternative energy future beyond the. dominant hydropower
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
Over the centuries, energy has been supplied by wood, coal, oil and natural gas, as well as by uranium. All these energy sources are limited and create pollution problems. This has led countries to focus on a sustainable ...
Assessment of energy and environmental performance of office building models: A case study
(Elsevier Science Sa, Lausanne, 2016)
