Finally, the influence of surface chemistry on biofilm attachment and performance was tested by facilitating biofilm growth on freely floating nylon and high-density polyethylene. Results indicate that organisms grown on more protected, sheltered carrier media respond to changes in mixing more rapidly than those on open and exposed media design.
Get PriceAn experimental analysis of the slot film cooling performance downstream of a mixing jet has been performed. The mixing jet was blown into the main flow at a position five jet diameters downstream of the slot exit. Flow visualizations of the jet and of the cooling film are presented for blowing rates of 1 and 2 with jet momentum rates of 7 and 10.
Get PriceThe PFF cell is an exception that shows much lower performance. A single polarization curve at 120 mL/min is shown at the bottom of Figure 6. The poor performance of the PFF cell can be attributed to low rates of vanadium transfer to the fibers in the electrode in the absence of forced convection.
Get PriceAll numerical investigations presented in this paper were carried out using a model geometry. No experimental results were available for this geometry. The validation of the code concerning film cooling mixing was presented in [15], [16], [17] and [18] (Vogel, 1994–1996).
Get PriceRiver plumes are generated by the flow of buoyant river water into the coastal ocean, where they significantly influence water properties and circulation. They comprise dynamically distinct regions spanning a large range of spatial and temporal scales, each contributing to the dilution and transport of freshwater as it is carried away from the source. River plume structure varies greatly among ...
Get PriceTherefore, consideration of fiber geometry and stiffness when choosing fibers for concrete overlays often becomes an economic choice, where the designer must balance cost, workability, and performance. Regarding the influence of the material on the residual strength, steel fibers often outperformed synthetic fibers by a significant margin.
Get PriceThe novel multi-step packaging concept is proposed in order to improve the voltage sharing performance. The proposed package geometry considers optimal dielectric isolation for each device leading ...
Get Pricegeometry of culture microchambers and microenvironmen-tal conditions (static and perfusion) influence cardiac cell proliferation, morphology, and alignment. Studies with verapamil hydrochloride, an L-type calcium channel blocker (CCB), were performed to check how culture con-ditions and the geometry of microsystems affect cell cyto-toxicity.
Get PriceUltra-high performance concrete is an important evolution in concrete technology, enabled by the combination of a good particle packing density, a suitable mixing …
Get PriceCongenital heart disease is the most common birth defect and functionally univentricular heart defects represent the most severe end of this spectrum. The Fontan circulation provides an unique solution for single ventricle patients, by connecting both caval veins directly to the pulmonary arteries. As a result, the pulmonary circulation in Fontan palliated patients is characterized by a ...
