(Uncorrected OCR) A bstract of thesis entitled "Mixing of a Non-Buoyant Multiple Jet Group in Crossflow" submitted by Md. Shahjahan Ali for the degree of Master of Philosophy at the University of Hong Kong in December, 2003 A submerged multiple jet group is an efficient environmental mixing device often used in waste water disposal systems and also found in natural environmental systems (e.g. bivalve currents on the sea bed) and anthropogenic activities. When a number of jets oriented in a line are discharged, the leading edge jets shelter the rear jets from the crossflow and produce a change in the mixing characteristics. This phenomenon has been reported in previous works, but no quantitative analysis has so far been made, and the three-dimensional jet interaction with the crossflow is still unresolved. In this study a comprehensive experimental investigation of the characteristics of a submerged multiple jet group (two to eight jets in a group) in crossflow has been performed under non-buoyant conditions, and the interaction of multiple jets with the crossflow is studied in the absence of strong boundary effect. A heuristic model is formulated to explain the interaction of jets in crossflow. Laser-Induced Fluorescence (LIF) and Acoustic Doppler Velocimetry (ADV) techniques are applied to study the concentration and velocity field respectively. The multiple jet interaction with the crossflow is explained through the experimental results of 2-, 3-, 4-, 6- and 8-jet groups, with a jet spacing of five jet diameters. To trace the individual flow path clearly, a series of experiments have been performed on multiple jets with individual jet isolation. The effect of jet spacing on mixing phenomena is investigated for a 2-jet group with a spacing ranging from 2 to 15 jet diameters. The crossflow momentum length scale of the experiments ranged from 1.6 to 15 jet diameters, which corresponds to a jet-to- ambient velocity ratio of 1.8 to 17.5. The effective crossflow velocit.

Practising engineers on site, in the design office or in client organizations will find this book an excellent introduction to the design and construction of sprayed concrete lined (SCL) tunnels. The complex behaviour of the early age behaviour of the sprayed concrete requires careful management. This book covers all aspects of SCL tunnelling – from the constituents of sprayed concrete to detailed design and management during construction. Although there is a close interdependence between all the facets of sprayed concrete, few engineers have the right breadth of experience and expertise, and this urgently needs to be transferred to the wider engineering community. Disseminating essential information for tunnelling engineers, Sprayed Concrete Lined Tunnels is key reading for all involved in or studying the process.
