Development of Tubular Solar Receiver with Supercritical Carbon Dioxide as Working Fluid
Over the past decade, solar powered supercritical carbon dioxide (s-CO2) based Brayton cycle has been identified as a promising candidate due to its potentially high cycle efficiency (50%, for turbine inlet temperatures ... -
Direct Estimation of Acoustic Source Characteristics of the Internal Combustion Engine Exhaust System and Analysis of Complex Muffler Configurations
Reduction in noise radiated from the IC engines is needed to meet the ever increasingly stringent noise regulations. The unmuffled exhaust noise of an IC engine is the biggest contributor to the overall engine noise. ... -
Direct Numerical Simulation of Square Vortex Flows
Atmospheric and oceanic flows are often modeled as two-dimensional due to their large planar extents (∼ 1000 km) and small vertical extent (∼ 10 km). Most phenomena in these systems are governed by the theory of two-dimensional ... -
Discrete particulate description of elastic structures undergoing geometrically nonlinear deformation and dynamic particle interaction
The mechanical behaviour of deformable bodies in a particulate environment has been an area of increasing interest across a wide spectrum of systems and scale. A composite ensemble of deformable structures and discrete ... -
Droplet Growth in Moist Turbulent Natural Convection in a Tube
(2018-07-04)Droplet growth processes in a cumulus cloud, beginning from its inception at sub-micron scale up to drizzle drop size of few hundred microns, in an average duration of about half hour, has been a topic of intense research. ... -
Dynamics of Bubbles and Drops in the Presence of an Electric Field
(2018-07-16)The present thesis deals with two-phase electrohydrodynamic simulations of bubble and droplet dynamics under externally applied electric fields. We used the Coupled Level-Set and Volume-of-fluid method (CLSVOF) and two ... -
Dynamics Of Cricket Song Towards Nature-inspired MEMS Speakers
(2016-09-15)The clever designs of natural transducers are a great source of inspiration for man-made systems. At small length scales, there are many transducers in nature that we are now beginning to understand and learn from. Here, ... -
Dynamics of Droplets Under Support, Acoustic And/Or Ambient Flow Excitation
(2018-04-24)The first step on the way to understanding the complicated dynamics of spray is to study the behavior of isolated droplets. In many industrial and natural processes such as turbulent combustion, agricultural sprays, spray ... -
