  • Caltech working to solve the world`s energy problems with the help of inVia

    Fossil fuels are the world's main fuel source for transportation, heating and generating electricity. As a by-product, high levels of CO2 are released into the atmosphere. With the drive for sustainable energy production, a method that generates easily-stored fuel from sunlight—and absorbs CO2—is a very attractive proposition. The California Institute of Technology ...

  • The case for water jet tank cleaning

    To maintain a consistently high level of product quality, today's processing plants must ensure that their tanks and reactors are thoroughly cleaned on a regular basis. The direct expenses involved can be substantial, and adding indirect costs {e.g., downtime and compliance with safety and environmental regulations) puts extreme pressure on tight operations budgets. To meet this challenge, more ...

  • Simulation of overflow nappe impingement jets

    Rectangular jets constitute one of the energy dissipation methods in the overtopping of dams. The high turbulence and aeration phenomena that appear in falling jets and dissipation basins make it difficult to carry out studies based only on classical methodologies. There are studies modelling spillways with computational fluid dynamics which produces accurate results. However, the study of ...

  • 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 ...

  • Jet fuel containment lagoon, Pittsburgh Airport, Pennsylvania

    Environmental responsibility takes top priority for the airforce reserve station at the Pittsburgh International Airport fuel facility. Thousands of gallons of jet fuel are stored and pumped each year, posing a significant environmental threat if the fuel was to reach ground water levels. In an effort to minimize storm water damage and environmental impact, engineers designed a detention pond ...

  • 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 ...

  • Replacement of Hot Caustic Paint Stripping Process with High Pressure Water Jet System: Ford Australia

    Ford Australia Ltd replaced an existing hot caustic paint stripping process, used for cleaning car skids, with a high pressure water jet system. This project has resulted in annual savings in the order of $300,000 from reduced chemical, energy and waste disposal costs. Significant improvements in paint quality were also achieved through the ability to clean the skids on a more regular basis than ...


  • 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 ...
