-
(University of Pretoria, 2022)Tyre forces are the primary external forces applied to a vehicle, especially at lower speeds, but are notoriously difficult to measure or predict. An intelligent tyre that allows the external forces to be determined from ...
-
(University of Pretoria, 2022)A recuperated solar-dish Brayton cycle using an off-the-shelf turbocharger as a micro-turbine and a rectangular cavity receiver with integrated thermal storage was considered for this study. Due to the high temperatures ...
-
(University of Pretoria, 2022)Advances made in Advanced Driver Assistance Systems such as Antilock Braking Systems (ABS), have significantly improved the safety of road vehicles. ABS enhances the braking performance and steerability of a vehicle ...
-
(University of Pretoria, 2022)The utilization of thermal solar energy has significantly increased in recent times. However, due to the daily temporal nature of solar irradiation, which is affected by, for instance, cloud coverage, efficient thermal ...
-
(University of Pretoria, 2020-02-15)The sustenance of industries depends on implementing energy conservation and sustainability concepts. They partially or wholly rely on thermal energy to fabricate products that are necessary for the paced livelihood. Amidst ...
-
(University of Pretoria, 2021)Recent developments in microelectronics have produced higher heat fluxes that are beyond the capabilities of current heat exchangers. An increase in computing power coupled with decreasing processor size requires high ...
-
(University of Pretoria, 2021-11)The development of an alternative wing-body-tail configuration is investigated using the AREND UAV as a baseline. The proposed configuration, inspired from bird wings, assumes that all stability requirements are achieved ...
-
(University of Pretoria, 2021)Presented here are the results from the steady state flow boiling of R245FA in a laboratory scale horizontal stainless-steel test tube with an inner diameter of 8.5 mm and a length of 900 mm at a saturation temperature of ...
-
(University of Pretoria, 2021)Concentrated Solar Power (CSP) also known as concentrated solar thermal is the systematic act of using mirrors and lenses to concentrate direct sunlight to a specific focal point so that solar radiation can be converted ...
-
(University of Pretoria, 2021)Statistics show that unstable articulated vehicles pose a serious threat to the occupants driving them as well as the occupants of the vehicles around them. An articulated vehicle typically experiences three types of ...
-
(University of Pretoria, 2020)The compromise between ride comfort and handling for a passive suspension system is a well-known and often researched problem. Semi-active suspension systems offer significant improvements to this compromise. One example ...
-
(University of Pretoria, 2021)Heat exchangers are used in a wide variety of industrial applications. Augmentation of heat transfer can realize a reduction in heat transfer size and increase the effectiveness and efficiency of heat exchangers. Heat ...
-
(University of Pretoria, 2019)With the export of coal being more lucrative than selling coal to South African power producers, power station operators might consider accepting lower-quality coal. While the impact lower quality coal has on cycle efficiency ...
-
(University of Pretoria, 2019)Recent technological developments, mostly in the fields of concentrated solar power and microelectronics, have driven heat transfer requirements higher than current heat exchangers are capable of producing. Processing power ...
-
(University of Pretoria, 2020)The aeronautical industry is among many which have focused on material with a high strength to weight ratios in order to accomplish as much efficiency as possible during flight. Among material of high strength to weight ...
-
(University of Pretoria, 2019)The reliable operation of Integrally Geared Centrifugal Compressors (IGCCs), used in the coal-fired power generation industry of South Africa, is essential for economic, environmental and safety considerations. However, ...
-
(University of Pretoria, 2020)Effective models of vibratory screens which can capture the true response characteristics are crucial in the understanding of faults and failures which occur in vibratory screens. However, the current available models are ...
-
(University of Pretoria, 2019)Reducing the rollover propensity of off-road vehicles while maintaining good ride comfort and off-road capabilities is a well-known challenge. With controllable suspension systems, the dynamics of the vehicle can be ...
-
(University of Pretoria, 2019)With autonomous vehicles being introduced around the world the possibility of controlling these vehicles from o -site locations presents itself as an opportunity to increase occupant/user safety as well as system e ciency. ...
-
(University of Pretoria, 2019)A feedwater heater is a typical component in power plants which increases the cycle efficiency. Over the last decade, renewable energies have significantly developed and been employed in the power grid. However, weather ...
