Laboratory experiments and field works play a crucial role in hydraulic research, development, design as many processes elude analytical formulation or, at least for the time being, are not readily nor accurately reproducible with numerical simulations [...]

In turbulent free-surface flows, the deformation of the surface leads to air bubble entrainment and droplet projections when the turbulent shear stress is greater than the surface tension stress that resists to the interfacial breakup. These complex processes at the water-air interface have been the focus of extensive experimental, numerical and theoretical studies over last two decades and thi...

IN T R O D U C T IO N Bridges are an integral part of any highway system. The design of a particular bridge depends on many variables. A major considera­ tion, often necessary, is the length of the bridge. In certain circum­ stances and locations the length may be dictated by factors other than cost. But, where necessary the designer must decide, “How far can the bridge approaches extend onto t...

This paper presents a new approach to the conceptual design of internally heatintegrated distillation columns (i-HIDiC), based on column temperature profiles analysis. The paper proposes tools to assess the thermal feasibility of i-HIDiC designs and to determine whether the design and operation are feasible from the hydraulics’ point of view.

In this paper a concept of an integrated water quality model for a river catchment area is presented. The main focus is directed to the development of a water quality module for rivers. Necessary simplifications for calculation of hydraulics and water quality will be explained. Furthermore, by first simulation results possible applications of the model are presented.

The main objectives of this paper are, designing and balancing of Water Distribution Network (WDN) based on loops hydraulically balanced method as well as using Geographical Information System (GIS) methodology with the contribution of EPANET. GIS methodology is used to ensure WDN’s integrity and skeletonized a proper and functional WDN by using Network Analyst utilizing the geometric network a...

The design of hydraulic systems is founded on deep physical connections. It needs creativity and, at the present time, it cannot be automated. Nevertheless, powerful design support in hydraulics is still possible. This paper presents a new view to the design of hydraulic systems and shows how sophisticated subtasks of the hydraulic design procedure can be tackled. We identify the “model synthes...
