Abstract:
Negatively buoyant jets develop when fluids are released upwards into a lighter fluid or, vice versa, downwards into a heavier fluid. There are many engineering applications, such as the discharge, via submerged outfalls, of brine from desalination plants into the sea. Some concerns are raised about the potential negative environmental impacts of this discharge. The increase in salinity is the major cause for environmental impact, as it is very harmful to many marine species. The diffusers for brine discharge are typically inclined upwards, to increase the path before the brine reaches the sea

Abstract:
AbstractWe use laboratory experiments and theoretical modeling to investigate the surface expression of a subglacial discharge plume, as occurs at many fjords around Greenland. The experiments consider a fountain that is released vertically into a homogeneous fluid, adjacent either to a vertical or a sloping wall, that then spreads horizontally at the free surface before sinking back to the bottom. We present a model that separates the fountain into two separate regions: a vertical fountain and a horizontal, negatively buoyant jet. The model is compared to laboratory experiments that are condu

Abstract:
An experimental investigation has been carried out on the flow and heat transfer characteristics of a horizontal buoyant ceiling jet that turns downward at a corner to yield a vertical negatively buoyant wall flow. Such flow situations are frequently encountered in thermal energy storage, in electronic systems, and in room fires. However, not much work has been done to understand the basic mechanisms governing such flows, particularly the flow near the corner. In this study, a two-dimensional jet of heated air is discharged adjacent to the lower surface of an isothermal horizontal plate. An is

Abstract:
The flow formed by the discharge of inclined turbulent negatively round buoyant jets is common in environmental flow phenomena, especially in the case of brine disposal. The prediction of the mean flow and mixing properties of such flows is based on integral models, experimental results and, recently, on numerical modeling. This paper presents the results of mean flow and mixing characteristics using the escaping mass approach (EMA), a Gaussian model that simulates the escaping masses from the main buoyant jet flow. The EMA model was applied for dense discharge at a quiescent ambient of unifor

Abstract:
ANFIS-type algorithms have been used in various modeling and simulation problems. With the help of algorithms with more accuracy and adaptability, it is possible to obtain better real-life emulating models. A critical environmental problem is the discharge of saline industrial effluents in the form of buoyant jets into water bodies. Given the potentially harmful effects of the discharge effluents from desalination plants on the marine environment and the coastal ecosystem, minimizing such an effect is crucial. Hence, it is important to design the outfall system properly to reduce these impacts

Abstract:
The two main wastewater discharges on the west coast of Australia, near the city of Perth, were monitored for their potential impact on phytoplankton communities between 1996 and 2000. The wastewater outlets varied in their location, length and depth (at point of discharge), volume of discharge and nutrient load. Phytoplankton responses were markedly different in the vicinity of the two outlets. In the vicinity of the southern outlet with the greatest effluent volume and nutrient load, phytoplankton responses were at or near the level of detection, except during summer.

Abstract:
Discharge of brine wastewater produced from industrial plants into adjacent coastal water bodies is considered as a preferable and common method currently used in many offshore industrial plants. Therefore, it is important to carefully study the behavior of jets and their environmental impacts on water bodies close to the discharge points, especially when the density is different between the jets and the receiving water. The main goal of this study is to improve the understanding of the mixing behaviour of jet trajectories for positively (offset) and negatively (inclined) buoyant jets when den

Artificial intelligence techniques have been widely used for prediction in various areas of sciences and engineering. In the thesis, applications of AI techniques are studied to predict the dilution of industrial outfall discharges. The discharge of industrial effluents from the outfall systems is broadly divided into two categories on the basis of density. The effluent with density higher than the water receiving will sink and called as negatively buoyant jet. The effluent with density lower than the receiving water will rise and called as positively buoyant jet. The effluent discharge in the

Abstract:
The proper design of the compartment ventilation system is an important requirement in the gas turbine industry. A poor ventilation system not only causes a circumferentially nonuniform casing temperature distribution, but also allows the formation of dangerous gas pockets inside the enclosure. Further, the presence of a circumferential casing temperature gradient has a negative impact on the operational efficiency of the turbine. Keeping the above design objectives in mind, a three-dimensional CFD analysis has been carried out using a leading commercial code to analyze the effectiveness of GE

Jet impingement has been extensively used in gas turbine airfoil internal cooling, especially leading edge and mid-chord region, which are subjected to high heat transfer loads. Earlier studies have shown that impingement onto dimpled surface results in higher heat transfer augmentation, particularly in maximum crossflow setting. The present study investigates the effect of Coriolis force and buoyancy in rotating channel featuring round shape jet plate and dimpled target plate, where the spent air is allowed to exit in only one direction, thus imposing maximum crossflow.
