Moratuwa Engineering Research Conference abbreviated as MERCon is the international conference organized by the Engineering Research Unit (ERU) of the University of Moratuwa. MERCon is an international multidisciplinary engineering research conference, which solicits research papers describing significant and innovative research contributions to all aspects of engineering. MERCon 2017 is the third...
Electric power transmission systems spread across large geographic areas present significant challenges to the engineers. Operating the system stably while maintaining voltage and frequency variations within narrow tolerance margins require careful long term planning as well as short term operational planning.
I am pleased to welcome you to Moratuwa Engineering Research Conference 2017. We feel greatly honoured to be able to host this International Multidisciplinary Engineering Research Conference for the 3rd consecutive time in 2017 at the University of Moratuwa, Sri Lanka. In addition to the main two day conference program, several keynote addresses and a series of workshops have been arranged to enhance...
For an extended period of time, the process industries have been relying heavily on modeling and simulation to improve their plant designs. Commercial as well as proprietary software tools are used for the validation of design models against plant data (pilot plant, full-scale reference plant, etc.), its adaptation to site specifications and its economic optimization. Economics generally improve further...
On behalf of the Program Committee, it is with great pleasure that I welcome you to the MERCon 2017 technical program at the Civil Engineering Complex of the University of Moratuwa.
A sustainable and environmental friendly polymer MEMS (Micro Electro Mechanical Systems) fabrication technology has been developed using thermal imprinting and polishing process. MEMS structures with minimum size of 2µm and maximum aspect ratio of 15 were formed by the polymer MEMS fabrication technology. In this paper, PMMA (Polymethyl methacrylate) which has several advantages such as lower fabrication...
Flooding in Colombo and environs has for many years been hampering public life and obstructing traffic and commercial activities on a regular basis. The flooding has three major causes: a) lack of outfall capacity, b) lack of storage capacity, and c) bottlenecks in the river and canal system (bridges, culverts, narrow river bends, blocking bridge piers/abutments, pipeline crossings, etc.).
Kapok (Ceiba pentandra) is a commonly available plant in Sri Lanka. Its application in waste water treatment, biomedical field and domestic uses is numerous. The purpose of this research is to investigate the effectiveness of nanocellulose extracted from Ceiba pentandra, as a filler in Polypropylene polymer matrix. Nanocellulose extracted from acid hydrolysis was further treated to avoid deterioration...
A three-dimensional particle model to describe the moisture distribution in copra for 20 hours of drying was developed using computational fluid dynamics. Drying experiments were performed for seven different temperatures in the range of 45 – 75 degrees of Celsius in a laboratory scale hot air dryer using copra samples of the dimensions 0.01×0.01×0.01 m3. Results of the spatial moisture distribution...
Lignin is considered as one of the most promising renewable resource for the future. Reduction of synthetic adhesive usage in wood composite production by the development of lignocellulosic materials is a challenge. Coir pith is abundantly available waste product which is rich in lignin. The chemical extraction protocols and mode of energy supply influence the structural changes which affects the...
Sludge generated in Central Effluent Treatment Plants (CETP) in industrial zones consisting of textile manufacturing, dying, finishing and garment washing has to be disposed of by the manufacturers. The current practice in Sri Lanka is to dispose the sludge by transporting it to a cement plant and incinerate it in a rotary kiln at a temperature lf around 1500°C. This is a costly solution due to the...
The measurement of ratio of product recovery in industrial methanol distillation is of high economic importance and represent a key performance index (KPI) of the distillation unit. In current operations, the product recovery of many industrial distillation units are not actively monitored, instead back calculated from daily production reports. The active monitoring of product recovery can be a costly...
Heavy metal toxicity due to industrial waste water is a one of a threat to environment and living organisms. In this research, adsorption experiments were carried out using jackfruit leave powder as a bio-sorbent was assessed for Lead (Pb) adsorption from synthetic waste water. The effect of pH of waste water, contact time, adsorbent dosage and initial concentration of waste water were studied in...
