The concept of Dynamic Spectrum Access (DSA), allows under-utilised radio frequency (RF) spectrum to be made available for Secondary Users (SUs) when not utilised by the Primary User (PU). A geolocation database is currently the preferred approach by regulators to deploy DSA in the TV-bands, i.e. TV white space networks. Central to the geolocation database is the computation node, responsible...

This study considers a numerical approach to identifying noise mechanisms in tandem
cylinders to understand aircraft landing gear as a primary contributor to airframe noise
during approach and landing. Fluctuations in the flow properties induced by turbulence
are computed as well as the corresponding propagations. A hybrid IDDES turbulence
model is employed, to compute the boundary layer...

Process equipment behaviour is characterised by multiscale multiphase interactions namely: liquid-gas, fluid-particle, particle-particle and particle-wall interactions. The understanding of these interactions, ideally, requires a general solution to the full turbulent Navier-Stokes equations combined with a unifying theory for granular flow. However, in the absence of such breakthroughs...

Pyrometallurgical smelting furnaces are used in the production of many commodities of strategic and economic importance in South Africa including ferrochromium, platinum-group metals, titanium dioxide, manganese alloys, and others. Most furnaces make use of tapholes, channels through the furnace wall and lining, in order to facilitate the removal of molten process material from inside the...

This talk focuses on the methodology taken in adjusting turbulence model coefficients based on historical data. The problem background as to why the turbulence model needed to be adjusted and how the HPC was able to generate data for surrogate model optimization.
The SST transition model as 1st described by Menter in 2001, makes use of empirical relationships to capture the effect of...
