  • AVA turbulence offers time saving and product protection - Case Study

    When pharmaceuticals have to be produced with as little solvent as possible and once all of the process-relevant options have been exhausted, there only remains the option of drying. This involves the acceptance of long, often very long drying times. Due to the loading of the dryer, the overall throughput capacity of the whole production plant is reduced. Even when the cycles are far shorter, ...

  • Second law analysis of a gravity–driven liquid film flowing along an inclined plate subjected to constant wall temperature

    The second law analysis of a gravity–driven liquid having temperature–dependent viscosity and flowing along an inclined heated plate was studied. The computational fluid dynamics (CFD) package FLUENT was used to obtain the velocity and temperature gradients, and the results were used to determine the entropy generation rate. Different cases of inclination angle and dimensionless parameters were ...

  • Jet Grouting to construct a Soilcrete wall using a twin stem system

    Abstract: An existing coal-loading pier located in Norfolk, Virginia was completed in 1961 for the purpose of loading ocean-going ships with coal for export throughout the world. The size of the ships that could be fully loaded at this facility was limited to the depth of the mud line adjacent to the loading pier. It was determined that dredging adjacent to the pier would provide an increase ...

  • Urban Stream Restoration: Standing Up to the Toughest Weather Conditions

    Project In 2008, the City of Altanta faced a large problem: the single-lane road that provides the only entry point to its SWAT team training center was likely to be lost completely to erosion. Although the road had been lined with concrete barriers as a stop-gap measure, it was clear that more substantial action was required to save it. Because the road is situated on a narrow ...

  • Anchorage systems for FRP strengthening of infill masonry structures

    An experimental research program consisting of 12 infill wall specimens was undertaken to investigate the effectiveness of several new and existing anchorage systems for fibre–reinforced polymer (FRP) strengthening of infill masonry walls. Specimens were loaded out–of–plane using an airbag to apply uniformly distributed pressure to the masonry. Test results indicate that the anchorage system had ...

  • Evolutionary data-modelling of an innovative low reflective vertical quay

    Vertical walls are commonly used as berthing structures. However, conventional vertical quays may have serious technical and environmental problems, as they reflect almost all the energy of the incident waves, thus affecting operational conditions and structural strength. These drawbacks can be overcome by the use of low reflective structures, but for some instances no theoretical equations ...
