Optimize the Efficiency of the Kaplan Turbine by Design and CFD Analysis of Runner Wheel Blades
Abstract: Abstract: Due to recent crises of electricity in the country, it is utmost need for the utilization of renewable energy resources abundantly available like hydropower. To overcome this problem of electricity shortage, hydro-power turbines can be used. Since every hydro site have different site conditions, so design and selection of the proper turbine type and size becomes more important. In this case, it is vital to adopt indigenous design and …

Short Review on the Effects of Plasma Processing Techniques in PMMA Microfluidic Device
Abstract: Abstract: The plasma processing techniques are useful for surface modifications on polymer surfaces. The appropriate surface modification alters the level of static contact angles on the polymer surfaces. The surface-driven microfluidic flow of suitable working liquid is sensitive to the static contact angle of microchannel surfaces fabricated by different polymers. Therefore, plasma processing techniques are suitable to vary the flow speed of working liquids in microfluidics. In future, this review …

Passive Capillary Flow of Aqueous Working Liquids in the PMMA Microfluidic Devices and SU-8 based Glass Microfluidic Devices
Abstract: Abstract: In this work, total 9 individual polymeric microfluidic devices are fabricated. The passive capillary flows of aqueous working liquids are studied in the fabricated polymethylmethacrylate (PMMA) microfluidic devices and SU-8 based glass microfluidic devices. All the microfluidic devices are fabricated inside the cleanroom laboratory. Dyed aqueous ethanol and dyed aqueous isopropyl alcohol (IPA) are the selected working liquids. CMOS camera is used to record each passive capillary flow in …

Performance Evaluation of Stream Powered Manometric Pump
Abstract: Abstract: Discharging the water from various sources like dams, wells, rivers, sea to fulfill various needs is not new objective. Windmills and river pump were the very old methods for discharge the water. Because of availability electricity the electrically operated pumps are the widely used devices for this purpose. Due to increase in awareness of the environment and increasing rates of electricity, it is again required to think about old …

Reduction in Stress Distribution in Horizontal Well Cementing
Abstract: Abstract: This paper addresses the stress distribution problem and effect on the cement behind the casing in the horizontal wells. The uneven stress distribution in the horizontal well causes crakes and breakage of the concrete which leads to various problems like instability of the bore hole in the affected region and secondly it paves path for flow of unwanted fluids in the cemented channels. Hence, to neglect this kind of …
