Chirp in a wavelength converter based on a symmetrical-MZI employing SOAs
A wavelength converter based on cross-phase modulation using semiconductor optical amplifiers (SOAs) in a symmetrical MZI is modelled. Since the model of the SOAs considers both amplitude and wavelength-dependent parameters ...
Simulations of high-aspect-ratio jets
There are many practical situations when jets are emanating from non-axis-symmetric apertures, yet numerical simulations of such three-dimensional jets are scarce and most of them have failed to reproduce some of the unique ...
3D extension of Bresenham's algorith and its application in straight-line interpretation
Conventional straight-line generating algorithms, such as the digital differential analyser (DDA), Bresenham's algorithm and the mid-point algorithm, are suitable only for planer straight lines on the coordinate planes, ...
Quantifying acceptable mesh dependencies for computational investigations of airflows within rooms
Ignorance of mesh dependency can sometimes be an embarrassment in numerical calculations. Mesh structures need to be developed to eradicate mesh dependency without compromising the finite computing resource and/or incurring ...
Behaviours of near two-dimensional ventilation configurations
Performances of eight configurations of a ventilated room are predicted. The flows exhibit increasingly three-dimensional tendencies as the proportion of wall occupied by the supply and extract vents is reduced. For all ...
