Valorization of Residual Ligno-celluloses from Anaerobic Digesters Through Product Recovery
Complete digestion of lignocellulosic biomass during anaerobic digestion (AD) is impossible due to recalcitrance created by lignin, consequently leaving behind a significant part of the feedstock unconverted to methane. ... -
Vaned Diffuser Effect on Centrifugal Compressor Performance and Stall
A centrifugal compressor is a mechanical device that helps to achieve higher pressure ratios at lower mass flow rates. It is used in many applications such as turbochargers, cruise missiles, and turbojet engines where ... -
Vapor Mediated Interaction in Droplets
Controlling internal flow in evaporating sessile droplets is desirable across applications ranging from lab-on-chip medical diagnostics, DNA profiling to surface patterning. Diffusion-limited evaporation in droplets exhibits ... -
A Variable Resolution Global Spectral Method With Finer Resolution Over The Tropics
(2010-11-19)Variable resolution method helps to study the local scale phenomenon of interest within the context of global scale atmosphere/ocean dynamics. Global spectral methods based on spherical harmonics as basis functions are ... -
Variation Of Marine Boundary Layer Characteristic Over Bay Of Bengal And Arabian Sea
(2016-05-04)The atmospheric boundary layer (ABL) is the lowest layer of the atmosphere where surface effects are felt on time scales of about an hour. While its properties are determined by the surface characteristics, season and ... -
Vertical Structure of Convective Clouds Using the TRMM PR Data
Very small fractional area (0.1%) occupied by the cumulonimbus (Cb) clouds belies their importance in Earths hydrological cycle and climate. For example, Riehl and Malkus (1958) estimated that the vertical transport of ... -
Vibration Analysis Of Structures Built Up Of Randomly Inhomogeneous Curved And Straight Beams Using Stochastic Dynamic Stiffness Matrix Method
(Indian Institute of Science, 2006-07-19)Uncertainties in load and system properties play a significant role in reliability analysis of vibrating structural systems. The subject of random vibrations has evolved over the last few decades to deal with uncertainties ... -
Vibration And Impact Induced Sound
(2010-10-22)Sound generated by impacting structures is of considerable importance in noise control. Sound is generated by a vibrating structure by inducing pressure fluctuations in the surrounding medium. Impact induced noise is the ... -
Vibration mitigation in spacecraft components using Stewart platform and particle impact damping
A spacecraft encounters two regimes of vibrations: launch loads and on-orbit loads. Both these loads propagate through the spacecraft structure, which is primarily made up of honeycomb sandwich. The launch loads that are ... -
Vibration Testing of Structures under Random Support Excitations
(2018-07-30)Vibration testing of structures constitutes a crucial step in design and commissioning of engineering structures. The focus here is on simulating field conditions in a laboratory so that detailed investigations of the ... -
Vibrational Energy Harvesting : Design, Performance and Scaling Analysis
(2018-07-12)Low-power requirements of contemporary sensing technology attract research on alternate power sources that can replace batteries. Energy harvesters function as power sources for sensors and other low-power devices by ... -
Viscous Vortex Method Simulations of Stall Flutter of an Isolated Airfoil at Low Reynolds Numbers
(2017-11-27)The flow field and forces on an isolated oscillating NACA 0012 airfoil in a uniform flow is studied using viscous vortex particle method. The simulations are carried out at very low chord (c) based ... -
Vision-based Strategies for Landing of Fixed Wing Unmanned Aerial Vehicles
(2018-05-14)Vision-based conventional landing of a fixed wing UAV is addressed in this thesis. The work includes mathematical modeling, interface to a software for rendering the outside scenery, image processing techniques, control law ... -
Vorticity and scalar transport in turbulent round jets with and without heating
The round turbulent jets are ubiquitous in both natural and engineered systems such as clouds, engine exhausts, chimney plumes, and respiratory flows. We aimed to understand the vorticity and scalar transport in turbulent ... -
Vulnerability of Forests to Climatic and Non-Climatic Stressors : A Multi-Scale Assessment for Indian Forests
(2018-06-05)During the 21st century, climatic change and non-climatic stressors are likely to impact forests leading to large-scale forest and biodiversity loss, and diminished ecological benefits. Assessing the vulnerability of ... -
Wall Effects In Packed Beds
(Indian Institute of Science, 2005-07-13)Packed beds find extensive application in a wide variety of industries. The objective of the present work is to analyze and evaluate the effects of the wall on structural characteristics, hydrodynamics and heat transfer ... -
Water Balance Studies In A Small Experimental Forested Watershed, South India
(2011-04-01)Forested watersheds play a dominant role in the global hydrological cycle. Very few experimental observatories especially in tropical forested regions of India have been undertaken. This study has been initiated for this ...
