A Review on working of Gas turbine Operation
Abstract: The basic operation of a gas turbine is a Brayton cycle with air as the working fluid. Atmospheric air flows through the compressor, increasing its pressure. Energy would then be tried to introduce by spraying fuel into the air and igniting it to build a high temperature flow. This superheated steam gas enters a turbine, producing shaft work output in the process. The unutilized energy can be generated in the …

Transforming Carbon: The Science and Potential of Gasification
Abstract: Methanol and chemicals like urea and ammonia, which are the building blocks of many fertilizers, can be produced via the gasification process. Additionally, gasification can assist in the production of transportation fuels from biomass, coal, oil, and sands. Drying, pyrolysis, combustion, cracking, and reduction are the five distinct thermal processes that make up gasification. Drying removes moisture from the feedstock, while pyrolysis breaks down complex hydrocarbons into simpler molecules. Combustion …

Design and Fabrication of Trammel Balls
Abstract: Transportation of water plays a vital role in the survival of a growing population. If the scarcity of water is one major issue, transportation of water using tankers have their own share. Water in a partially filled container, when induced with external energy (motion), generates slosh and surge. Both slosh and surge effects work as a resistive factor during transportation. To eliminate the same, few holes are drilled at pre-desired …

Laser-induced Phosphorescence Photobleaching Anemometer for Microfluidic Technology Instruments
Abstract: In this article, we have established a new, non-intrusive flow velocity calculation approach focused on photobleaching of a fluorescent dye for micro-fluidic systems. The time of existence of the fluorescent dye in the laser beam depends on the flow rate which roughly relates to the time of decay of the photobleaching of the dye in the laser beam. The time of residency is inversely proportional to the speed of flow. …
