ENGLISH ABSTRACT: A wet-cooling tower fill performance evaluation model developed by Reuter is derived in Cartesian coordinates for a rectangular cooling tower and compared to cross- and counterflow Merkel, e-NTU and Poppe ...

ENGLISH ABSTRACT: The use of micro gas turbines (MGTs) for the propulsion of unmanned aerial vehicles (UAVs) has become an industry standard. MGTs offer better performance vs. weight than similar sized, internal combustion ...

ENGLISH ABSTRACT: The majority of power stations in South Africa are located in coal rich, but arid regions where wet-cooled condenser systems are not feasible from an environmental and economic perspective. Consequently ...

ENGLISH ABSTRACT: Conventional concentrating solar power (CSP) plants use Rankine cycles as their thermal power generation cycle. Recent developments have shown the potential for combined cycle (CC) CSP plants to achieve ...

ENGLISH ABSTRACT: An existing three-dimensional fluid mechanical design of a compressor is reviewed and compared to mean-line simulation results obtained using the Comp- Aero® compressor design code. Mean-line simulation ...

ENGLISH ABSTRACT: This thesis presents a novel method of parametrization and optimization for a large design space exploration of a micro gas turbine compressor stage. 48 free parameters were used to control the meridional ...

ENGLISH ABSTRACT: Large air-cooled heat exchangers are used to cool process fluids in thermodynamic cycles in a range of industrial processes. These systems consume less water than wet-cooled systems and thus have major ...

ENGLISH ABSTRACT: In recent times the demand for Micro Gas Turbines (MGTs) with power levels below 10 kW has increased. Despite MGTs being a potential replacement of internal combustion (IC) engines, they are prone to ...

ENGLISH ABSTRACT: The ineffective utilisation of refrigerated container's (RC) space is a pressing problem for the South African fruit industry. Current packaging systems do not optimally make use ofthe refrigeration ...
