CFD Modeling in Water & Wastewater Treatment


Mazzei uses multiphase flow modeling to design, analyze and optimize our individual products as well as multi-component contacting systems. Computational Fluid Dynamics (CFD) combines computational methods with engineering physics, chemistry and mathematics to solve complex fluid flow challenges. Dr. Srikanth Pathapati heads Mazzei’s in-house Computational Fluid Dynamics Department. Dr. Pathapati holds a PhD in Environmental Engineering from the University of Florida and brings over a decade of CFD experience to Mazzei. With CFD, Mazzei possesses the capability for multiphase flow modeling incorporating turbulent flow regimes, gas volume fractions, bubble size distributions, chemical reactions, species transport, local mixing, mass transfer and more.

Advanced simulation tools, including state-of-the-art ANSYS Fluent and CFX simulation software, power Mazzei’s solutions to fluid flow problems and enable a fast, informed and streamlined design and manufacturing process. The combination of over three decades of proven design experience, diligent and robust modeling practices coupled with careful physical experimentation, allows Mazzei to design and optimize mixing and mass transfer performance in new equipment and to troubleshoot already existing installations.

Mazzei is able to solve problems before they occur; and where problems exist in a current system, we are able to help customers pinpoint them and develop solutions. Whatever your operation or application – whether you’re mixing or contacting, aerating or irrigating – see how Mazzei can deliver a more cost-effective solution.
