The aim of this study is to understand the microscopic behavior of heat and momentum
transfer in nanofluids. With nanofluids reporting enhanced thermal conductivities (𝜅)
and viscosities (𝜂), a microscopic understanding ...
An analysis of global, beam and diffuse solar radiation on horizontal and 7° tilt about east west axis and facing due south orientation at Hambanthota was carried out to assess the solar resource potential in dry zone of ...
Solar photovoltaic (PV) is penetrating electrical grids with a substantial growth of new additions, as a result of renewable energy policies and plans implemented locally and globally. However, the intermittent nature of ...
Open sun drying is the widely used passive method for black pepper drying, but due to its
limitations such as unavailability on rainy days, lack of controllability, degradation of food
quality, loss of volatile oil, and ...
Microfluidics has recently gained research attention for its high-end thermal
applications, including micro heat exchangers, Lab on a Chip, micro reactors, and
MEMS. It has been proven that the addition of suitable ...
This work relates to the design and development of Shape Memory Alloy (SMA) based novel
actuators for Minimally Invasive Surgeries (MIS). Compared to conventional open surgery,
MIS procedures are favorable and developments ...
In the beginning, humans used architecture to protect their selves from nature and unsteady
environmental conditions. However, with time, modern buildings become more complex,
which need to fulfil the different types of ...
Physical phenomenon of the relation among ground-level ozone (O

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 ...
The wellbeing, comfort, and satisfaction of office occupants are all influenced by the
indoor air quality (IAQ). As such, it is important to maintain good IAQ in offices.
However, several studies say that Sri Lankans ...
Buildings are responsible for about 40% of global energy consumption, 42% of global CO2 emissions and about 30% of global fresh water consumption. Therefore, the importance of energy and water consumption benchmarking in ...
The manufacturing sector accounts for nearly 40% and 25% of global energy and resources
consumption respectively. The die and mould manufacturing (DMM) sector, contributes
largely to the energy and resource consumption ...
Knittability specially in synthetic yarns such as polyester and nylon is an essential index
of the performance in ensuring the proper conversion of yarn to a knitted fabric. This can
be affected by various conditions of ...
There are only three combined cycle power plants in Sri Lanka. Ceylon Electricity
Board owns one power plant, and private companies own the other two. Combined
cycle power plants start-ups can be divided into three ...
Due to the fossil fuel prices and depleting storage capacity, as well as growing concerns about global climate change, the use of renewable energy (RE) on a national scale has become essential for any country in the world. ...
Steam boilers constitute an important part of a production facility. Though traditionally, fossil fuel has been used predominantly in steam boilers, the environmental impacts of using fossil fuel and the higher economics ...
Demand for electricity during a day, varies with the time due to various factors. Electricity demand of Sri Lanka for a typical day could easily be divided into three main categories. One segment characterizes a very high ...
Waterproofing is the process of rendering an object or surface resistant to water. Importance of waterproofing in construction cannot be overstated. It is essential for durability, hygiene and also for a pleasant appearance. ...
Energy consumed in the building sector consists of residential and commercial end
users and it accounts for 20.1% of the total delivered energy consumed worldwide
[22].Global primary energy demand is projected to increase ...
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. ...
