Analysis of the embodied energy in cement produced in Sri Lanka was carried out considering national boundaries. National energy input to the cement manufacturing was the main focus or this study and therefore any energy ...

Diffused shaped holes have shown superior cooling performance over the other shapes of holes in many situations. In the present study, numerical simulation using realizable k-ε model with enhanced wall treatments as ...

Energy productivity is a critical factor for the Sri Lankan manufacturing industries which is a critical issue that affects the cost of production. Efficiency in consumption of energy and its conservation would be one of ...

Currently the mixed municipal waste as well as the source segregated household and commercial waste from eight local authorities is disposed at the Karadiyana waste-processing site. A small fraction of the source-segregated ...

Analysis of free surface vortices formation in a horizontal type water intake structure of Samanala Power Station has in this study been carried out with the help of “Flow-3D” Computational Fluid Dynamic software. A numerical ...

Conduction, convection and radiation are the principle modes of transferring heat from a source to sink. In a furnace, when the operating temperature is above 10000C, radiation heat transfer will be the predominant mode ...

Increasing passenger density makes indoor state of train compartments not thermally comfortable. Air conditioned train compartments have been introduced to provide comfortable pleasant interior environment to the passengers. ...

Economic potential of energy conservation in a five star hotel was established. The selected site was the Hotel Lanka Oberoi, Colombo. The electrical energy demand and the thermal energy demand of the hotel were assessed ...

In this research project, characteristics of mini hydro power schemes which affect to the performance of the scheme were analyzed. The main objective of the project was to develop an analytical criterion to estimate the ...

Compared to the other countries in the region, Sri Lanka has a deep penetration of approximately 75% of grid electricity. However, providing electricity every rural household is a difficult goal, without employing off-grid ...
