Laser-based Diagnostics and Numerical Simulations of Syngas Combustion in a Trapped Vortex Combustor
(2017-11-16)Syngas consisting mainly of a mixture of carbon monoxide, hydrogen and other diluents, is an important fuel for power generation applications since it can be obtained from both biomass and coal gasification. Clean coal ... -
Late Cenozoic climate reconstruction from the Northern Indian Ocean using foraminiferal clumped isotope thermometry and stable isotope technique
The Late Cenozoic era (23.03 million years ago to the present) offers a critical time window to examine the role of greenhouse gases, notably CO2 (ranging between 910 ppm and 180 ppm), in the operation of Earth's system ... -
Lattice Boltzmann Relaxation Scheme for Compressible Flows
(2018-03-09)Lattice Boltzmann Method has been quite successful for incompressible flows. Its extension for compressible (especially supersonic and hypersonic) flows has attracted lot of attention in recent time. There have been ... -
Lattice Boltzmann Relaxation Schemes for High Speed Flows
The lattice Boltzmann method (LBM) has emerged as a highly efficient model for the simulation of incompressible flows in the last few decades. Its extension to compressible flows is hindered by the fact that the ... -
Lay Tracks : New approach to automated quadrilateral mesh generation using MAT
This thesis describes Lay Tracks, a new mesh generation algorithm to automatically generate an all quad mesh using the medial axis transform (MAT). LayTracks combines the merits of two popular direct techniques for quad ... -
