Free surface flows over submerged obstructions
Steady and unsteady two-dimensional free surface flows subjected to one or multiple disturbances are considered. Flow configurations involving either a single fluid or two layers of fluid of different but constant densities, are examined. Both the effects of gravity and surface tension are …

Waves Generated by Moving Vessels and Cnoidal Wave Interactions with Either a Partially-submerged Porous Barrier or a Mixed Partially-submerged and Submerged Dual Porous-Barrier System
… types of porous breakwaters. One is a partially submerged porous barrier and the other one is a dual-barrier system consisting of a complete submerged frontal porous wall and a partially submerged rear porous wall. For both breakwater systems, the unknown coefficients of the velocity potentials …

The development of filamentous fungi in submerged culture
… on the subsequent growth of filamentous fungi in submerged culture. This early phase of growth does not appear to have received much attention, and it was for this reason that the author's research was started. The aggregation, germination and early growth of the filamentous fungus Aspergillus …

Mass Transfer Characteristics of the Submerged Liquid Jet
Mass transfer characteristics of a liquid jet in a liquid continuous phase have been studied using a captured jet technique. A vertical jet was formed at the centre of a glass sided square-section cell of 102mm x 102mm x 305mm which held the stationary continuous phase. The technique allowed the …

Transient model of preheating a submerged entry nozzle
Adequate preheating of the submerged entry nozzle (SEN) is important to avoid problems such as thermal cracks and skulling, and depends on torch configuration, fuel, SEN geometry and other factors. A steady-state axisymmetric computational model of the flame, combustion reactions, and air …

Submerged-Membrane Bioreactor for the Treatment of NASA Wastewater
… in a microgravity compatible manner.A novel submerged-membrane bioreactor was constructed to examine the treatment efficiency of a NASA wastewater ersatz. The bioreactor utilizes both anoxic and aerobic processes for carbonaceous and nitrogenous species removal. While complete biological …

Protection of electronics in submerged enclosures against underwater explosions
In the milieu of military sea mine design, it is often necessary to design mines that are to be placed at small distances from each other. A possible tactical purpose may require that each mine be set to explode at controlled instances in time without disturbing the operation of the other mines in …

A field investigation of diffusion within a submerged plant canopy
Saltwater marshes and wetlands are important buffers at the land-sea interface. Among the most biologically active ecosystems on Earth, natural and man-made wetlands are important interceptors of pollutants and nutrients bound for the coastal ocean. The transport, dilution, and deposition processes …

Submerged combustion of premixed hydrocarbon-oxygen flames in liquid nitrogen
… holder near room temperature even though it was submerged in liquid nitrogen. Three premixed flames, CH₄-O₂, C₃H₈-O₂, and C₂H₂-O₂, were studied. The submerged stoichiometric combustion yielded condensed products, which, when mass spectrometrically analyzed at room temperature, consisted of …

High resolution seismology, archaeology and submerged landscapes - an interdisciplinary study
… correct spatial and contextual relationships of submerged archaeological structures. To facilitate survey of the shallow intertidal zone, a novel catamaran-based platform is developed, which carries side scan and Chirp sub-bottom sonar systems, and is proved operational in water depths greater …

The analysis of acoustic noise in a submerged arc furnace
… project deals with Acoustic Noise Analysis in a submerged Arc Furnace. Operators and Metallurgists believe that the acoustic noise coming from the furnace conveys information as to the operating conditions of the furnace. This submerged arc furnace reduces ferrochrome ore to the metal. A …
