  • Cavitation leads to perfect mixes

    Development of accurate classification of cavitation types, as well as any classification, has to be based on a choice of general summary classification signs. For example, it can be different by constructive signs of work parts, by character of a course of process, by cavities types and other general classification signs. In present time distinguish the following types of cavitation: static, ...

  • Integral Model for Turbulent Buoyant Jets in Unbounded Stratified Flows Part 2: Plane Jet Dynamics Resulting from Multiport Diffuser Jets

    Abstract  An integral model for the plane buoyant jet dynamics resulting from the interaction of multiple buoyant jet effluxes spaced along a diffuser line is considered as an extension of the round jet formulation that was proposed in Part I. The receiving fluid is given by an unbounded ambient environment with uniform density or stable density stratification and under stagnant or steady ...

  • A turbulent submerged swirling jet expansion in still air and entropy generation

    Gas jets find cooling and heating applications in industry. The swirling of jets improves flow mixing in the jet and modifies the flow structure significantly. In the present study, an isothermal submerged swirling air jet expanding into still air is considered and entropy generation, due to fluid friction in the flow field, is formulated and computed for different values of swirl number. It is ...

  • KLa Jet Aerators/Mixers for Large Diameter Equalization Tanks - Case Study

    Flow Equalization Many municipalities are facing the challenge of having to equalize large volumes of storm water sometimes mixed with raw sewage in order to continuously meet their permit limitations. The equalized flow is stored during a storm event and then slowly diverted to the treatment facility when influent flows return to normal levels.  In the past few years the need ...

  • Rotary batch blenders help DIP get pre-mixes to market fast

    Mixers are more efficient than double-cone units Ductil Iron Powder (DIP), Buzau, Romania, was established in 2000 as a spin-off of Ductil Steel. Its products are iron and alloyed powders for use in powder metallurgy and welding applications. The plant for making the iron powders began operation in 1995, and by 2000 it reached its current capacity ...

  • Study of dilution, height, and lateral spread of vertical dense jets in marine shallow water

    This study provides information for the design of sea outfalls to dispose of brine from desalination plants into shallow lagoons of the sea. The behavior of vertical dense jets was studied experimentally by discharging cold saline water vertically upward into a tank filled with hot freshwater under stagnant ambient conditions. The minimum return point dilution, μmin, was determined ...

  • 5 Must Do Steps to Keep Your Jet Aeration System Running Smoothly

    Sustained low dissolved oxygen levels in an aeration tank can cause a host of problems — including difficulties in maintaining soluble BOD (biochemical oxygen demand), reduced nitrogen removal efficiency, and challenges with biomass separation. A jet aeration system offers a solution, utilizing both a pump and blower to meet the oxygen transfer requirements of a biological process. A well ...

  • Development and application of 3D numerical model THREETOX to the prediction of cooling water transport and mixing in the inland and coastal waters

    A modelling system—THREETOX—has been developed to simulate the transport and mixing of cooling water in both freshwater and marine environment. A 3D hydrostatic free-surface model describes the heat dispersion in the far-field, whereas an integral buoyant jet model coupled with a far-field model is applied to the near-field. The equations of hydrodynamics of the far-field model are ...

  • 10 Questions (And Answers) That May Change the Way You Aerate

    Slot Injector: How does the slot-shaped nozzle of the Slot Injector™ aeration system improve performance? The slot shaped nozzle and mixing chamber provide a larger shear surface for mass transfer than a circular jet of identical area. This unique shape results in a high percentage of gas dissolution and superior oxygen transfer rates with a 10-20% reduction in energy usage ...

  • Cement industries solution to Waste Management - Remediation of oil refinery sludge basin

    Abstract Work was completed in early 1992 to clean up a 5.5 acre (2.2 ha) stormwater sludge basin for an oil refinery company. The basin, which had served as a stormwater collection and settling pond for over 40 years, contained oily sludges with high concentrations of certain metals and volatile organic compounds. The closure plan included a combination cement-bentonite slurry wall and jet ...
