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 ... -
Vapour phase catalytic hydrogenation of aniline
A very large effort has been directed towards heterogeneous catalysis and establishing the proper form for equations that express the rate of surface reactions as a function of system variables. These equations range ... -
Vapour phase oxidation of p-xylene
The kinetic study on the oxidation of p-xylene has been carried out. The oxidation of p-xylene on the following two catalysts has been studied: (a) tin vanadate (b) ferric molybdate (Boreskov’s composition) Ferric molybdate ... -
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 ... -
VENTURI STUDIES WITH WATER ON CAVITATIOK INCEPTION CAVITY CHARACTERISTICS AND CAVITATION EROSION BEHIND BLUFF BODIES
Cavitation is defined as the formation, growth and collapse of vapour or gas? and vapour?filled bubbles in a liquid subjected to reduced pressures (of the order of the vapour pressure of the liquid) at constant ambient ... -
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 ... -
Virtual Element Methods for Phase Field Fracture: Mesh Transitions, Composite Damage, and Stabilization-Free Formulations
Accurate simulation of crack propagation requires discretization methods that combine geometric flexibility with computational efficiency. Although the finite element method (FEM) and its variants remain the widely used ... -
