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 ... -
Wave Propagation in Adhesively Bonded Single Lap Joints: Solution of Forward and Inverse Problems
The use of adhesives for bonding composites as well as metals is rapidly increasing since it provides uniform load transfer and is free of stress concentration seen around the drilled holes in bolted or riveted joints. ... -
Studies on Processed Granulated Blast Furnace Slag as Fine Aggregate in Mortars and Concrete
Fine aggregate is essential for the preparation of mortar and concrete. There are attempts to find alternatives to the river sand as the natural sources for fine aggregates are dwindling. Currently, sand mining from river ... -
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, ... -
Design of Curved Aggressive Annular Diffusers
For economical air transportation, aero engines with lower specific fuel consumption, lower emissions and lower noise levels are required. To this end, the use of turbofan engine with high bypass ratio is an option. With ... -
