(2018-08-10)The current work, through experimental and numerical investigations, analyses the process and cycle level deviations in engine response on fuelling multi-cylinder natural gas engines with producer gas. Producer gas is a ... -
Integrability Evaluation Methodology for Building Integrated Photovoltaic's (BIPV) : A Study in Indian Climatic Conditions
(2018-01-02)India’s geographical location renders it with ample solar-energy potential ranging from 4-7 kWh/m2 daily and 2,300–3,200 sunshine hours annually. The diverse nature of human settlements (scattered low-rise to dense high-rise) ... -
Integrated Wastewater Management for Tank Restoration in Urban Fringe Areas
Urban fringe water bodies are often seriously affected by urban wastewater including partially treated sewage entering it and degrading it. Sustainability requirements necessitate that such wastewaters are treated and ... -
Investigating the role of moisture in vernacular and conventional building typologies for occupant comfort and health
Moisture is omnipresent and critical to sustain life on the planet. In buildings, it is observed in the form of indoor moisture, dampness on walls, seepages, etc. As building occupants, humans perceive moisture in the air ... -
Investigations into Incineration of Sanitary Napkin Waste Using Single Chamber Incinerator
Commercially available disposable sanitary napkins are the most common method of menstrual hygiene management in most urban regions of India (van Eijk, 2016) (Mathiyalagen et al., 2017). It is estimated that in India a ... -
Investigations into the Thermo-chemical Conversion of Simulated Refuse Derived Fuels with Different Plastic Contents
The burgeoning problem of municipal waste generation along with its disposal problem has urged the development of sustainable waste management practices such as waste-to-energy conversion. Refuse-derived fuel (RDF) represents ... -
Isolation of Arsenic and Sodium Hydroxide Recovery Using Nanofiltration for a Zero-waste Arsenic Remediation Scheme
Groundwater contamination by arsenic poses a significant global health concern, with even trace concentrations leading to severe health issues, including various cancers and cardiovascular diseases. Conventional arsenic ... -
Lignin and Extractive Tracing - an Alternative approach to Assess and Predict Biogas Yields and Production Rates among Tropical Biomass Feedstocks
Predicting biogas yields from the composition of biomass feedstocks has been difficult primarily due to the variations found in their chemical composition and structure of lignocellulosics. This study aims at understanding, ... -
Low Head Hydraulic Pumping – Design, Simulation, and Field Validation of Ram and Turbine Pump in Indian River Basin
Water energy is essential for economic expansion and human development. Social progress and economic growth depend on meeting water energy needs sustainably. The use of non renewable energy sources for pumping water to ... -
Methanol Synthesis from Simulated Bio-syngas: Experimental and Modeling Studies
Methanol is increasingly being considered as an alternative fuel due to its potential to reduce environmental pollution and its ability to be used directly in internal combustion engines without any engine modification. ... -
Modeling and Analysis of Hybrid Renewable Energy for Power Generation
Renewable energy-based power has gained significant global momentum—to minimize fossil-fuel use, combat climate change, and ensure energy security. While renewable energy (RE) is fast-growing, stand-alone single resource-based ... -
Multi-component Gas Mixture Separation: Fundamental Studies to Pilot Scale Development and Characterization
Climate change has become one of the significant challenges of the 21st century resulting in increased demand for low-carbon energy carriers to achieve a sustainable future. Thermo-chemical conversion of environmentally ... -
Preliminary Investigation into the Cold Plasma Powered Water Gas Shift Reaction – Experiments And Analysis
Water gas shift reaction (CO + H2O ↔ H2 + CO2) is a CO oxidation reaction in the presence of steam resulting in the formation of H2 and CO2. Traditionally, water gas shift (WGS) reaction is achieved using multiple catalytic ... -
Prospects of Bioethanol from Estuarine Macroalgae
Burgeoning dependence on fossil fuels for transport and industrial sectors has been posing challenges such as depletion of fossil fuel reserves, enhanced greenhouse gas (GHG) footprint, and imminent changes in the climate, ... -
Reliability Based Approach for Evaluation of MSW Landfill Designs and Site Selection using GIS
(2018-02-28)Dumping of municipal solid waste (MSW) generated due to anthropogenic activities in any barren land or out fields causes severe hazards to human populations, ecosystems and the environment. In order to avoid this, it is ... -
