CFD for Water & Wastewater Treatment: Oxidation Ditches
An oxidation ditch is a type of biological wastewater treatment process that uses a circular or oval-shaped circulation channel with aeration devices to promote the growth of microorganisms that degrade organic pollutants.
One of the main challenges of designing an oxidation ditch is to optimize the aeration system and mixing equipment in combination. This has a significant impact on energy consumption and process efficiency.
As the overall hydrodynamics of the system is key to ensure reliable operation in an oxidation ditch, CFD simulations become an essential tool to study the flow behavior at design stage before the building has started.
We can conduct real time simulations of oxidation ditches with an unparalleled degree of accuracy and get a unique and detailed view of the flow behavior and analyze key elements such as mixing patterns, aeration efficiency, suspension of solids, etc.
More than 25 years of experience innovating and developing revolutionary solutions allow us to provide unique and in-depth analysis and solutions.
MSTAR is an advanced Lattice-Boltzman solver, optimized for running efficiently on GPU's, and that is tailored for applications in the water, process, chemical, and pharma industries.
As an official partner of MSTAR Simulations, we offer this powerful software alongside comprehensive support services. This includes training, seminars, and technical assistance to guarantee your success in conducting productive CFD simulations

CFD for the Water & Wastewater Industry: Simulation of Moving Bed Biofilm Reactors (MBBR)
Переглядів 2224 місяці тому
Simulating Moving Bed Biofilm Reactors (MBBR) using Computational Fluid Dynamics, presents significant challenges! Given that MBBR tanks house hundreds of millions of carriers, each ranging from 1 to 5 centimeters in diameter, a comprehensive simulation must accurately model individual drag forces, account for collision dynamics between carriers, and predict their collective impact on fluid flo...
CFD in Industrial Mixing: Mixer sizing for solids suspension
Переглядів 2,4 тис.Рік тому
We have conducted two separate CFD simulations comparing the impact of mixer diameter versus tank diameter on particle suspension. The tank in both cases was cylindrical with a diameter and water height of 1.0m, and featured 4 baffles to enhance axial flow. The mixer diameter in the first simulation was 1/3 of the tank diameter, and in the second it was increased to 2/3 of the tank diameter. De...

    How are you combating numerical diffusion in laminar passive scalar case?

    • @thinkfluiddynamix4834
      @thinkfluiddynamix4834 Рік тому

      Hi! numerical (or false) diffusion happens mostly with 1-order upwind schemes. These simulations are calculated using a Lattice-Boltzmann Method solver. The explicit time-scheme, together with a very small time-step (Courant number = 0.03) and a very high resolution (50 Million lattice points) makes sure that we do not have any problems with numerical diffusion.

      LES because you literally cut the vórtices you can resolve in a simulación with a filter that is defined by your mesh size. With RANS you are avergaing, you aren't really watching any vortices.
