A framework to promote mould remanufacturing in Sri Lankan sme

Wanaguru, BK; Gamage, JR [Conference-Full-text]

The global mould manufacturing market amounts to USD 26.21 billion in 2020 and is expected to increase to USD 38.62 billion in 2025 at a Compound Annual Growth Rate (CAGR) of 8%. This growing demand for moulds urges to ...
Chitosan-graphene oxide composite membrane for methylene blue removal

Dissanayake, NSL; Pathirana, MA; Wanasekara, ND; Nandasiri, GK [Conference-Full-text]

Textile wastewater accommodates many toxic organic contaminants which could potentially threaten the ecosystem if left untreated. Methylene blue is a toxic, nondegradable, cationic dye which is reportedly found in significant ...
Influence of repeat unit size on the auxetic effect of foldable weft knitted fabrics

Madhurangi, C; Wijethunga, C; Lanarolle, G [Conference-Full-text]

General phenomenon of engineering materials is to reduce the width when stretched. The auxetic materials expand in the lateral direction when stretched and contract when compressed, giving a negative Poisson’s ratio. This ...
Copper nanoparticle synthesis on plasma treated poly(lactic) acid nonwoven fabrics

Rathnayaka, NC; Nandasiri, GK; Wanasekara, ND [Conference-Full-text]

The demand for antibacterial fabric surfaces is increasing day by day. With the covid-19 pandemic situation, there is attention to antibacterial and antiviral nonwoven fabrics which can be used towards the development of ...
Numerical study to investigate the pressure propagation patterns by a compression sleeve with miniaturised air-bladders

Hedigalla, D; Ehelagasthenna, M; Nissanka, ID; Amarasinghe, R; Nandasiri, GK [Conference-Full-text]

Chronic venous disease (CVD), the most prevalent vascular disease affecting to the lower extremities, is regarded as any functional or morphological abnormalities of the venous system. Compression therapy, either active ...
Reducing the excess energy consumption on higher ventilation flowrates to control the co2 levels of the central air conditioning systems in polluted urban areas by co2 capturing

Wijewardane, MA; Herath, HMPD; Ranasinghe, RACP [Conference-Full-text]

Controlling the air quality of the indoor environment is extremely important to improve the health and the productivity of the occupants. The air quality is maintained by providing ventilation air following the ASHRAE ...
Heat transfer enhancement in microchannels with liquid - liquid slug flow using al2o3 nanoparticles

Siriwardana, G; Bandara, T; Ranasinghe, C [Conference-Full-text]

Non–mixing two-phase flows in microchannels have become a popular technique for cooling applications due to their thermal performance and flow generation simplicity. Slugflow is one of the regimes in two-phase flow that ...
Development of a numerical model for pollutant dispersion over 3d building array

Inparaja, S; Narayana, M [Conference-Full-text]

A CFD solver was developed by using OpenFOAM software to predict the pollutant’s dispersion over a 3D building array. A simulation mesh setup was created to replicate an actual urban environment, where the dispersion ...
An analytical approach for designing turbo expanders for organic rankine cycle

Ratnayake, RMSA; Bandara, RMAT; Sandaruwan, PHPL; Wijewardane, MA; Ranasinghe, RACP [Conference-Full-text]

ORCs (Organic Rankine Cycles) are becoming widely attractive for waste heat use since they facilitate power generation from low thermal content supplies. ORC may be optimized in various ways after determining the appropriate ...
Energy efficiency enhancement of container boxes converted as living spaces (convertainers)

Wanigasooriya, DM; Bandara, HMLT; Wijayasiri, YI; Wijewardane, A [Conference-Full-text]

The use of discarded shipping containers as temporary living spaces at construction sites, industrial facilities, and commercial applications, is progressively increasing due to several advantages such as mobility, cost ...
A theoretical model to analyze the draft force and power requirement of a tillage implement consisting of both a disc plough and a subsoiler

Elangasinghe, A; Fernando, P; Colombage, J; Perera, S; Subasinghe, LU [Conference-Full-text]

The draft force and power requirements of tillage equipment are important metrics for agricultural equipment designers. Yet, a theoretical model to find these metrics for combined tillage equipment is lacking. To overcome ...
