Environmental Technologies, Inc. provides world class consulting in fluid
dynamics with a specialty in computational modeling of fluid dynamic (CFD) systems
(see Statement
of Qualifications-
Our main analysis tools are well established commercial CFD software packages.
raditional restrictions
in flow analysis and design limit the accuracy in solving and visualization of the
fluid-flow problems. This applies to both single and multi-phase flows, and is
particularly true of problems that are three dimensional in nature and involve turbulence,
chemical reactions, and/or heat and mass transfer. All these can be considered together in
the application of Computational Fluid Dynamics, a powerful technique that can help to
overcome many restrictions influencing traditional analysis.
heoretically, it should
also provide an opportunity for relating these to other process conditions, such as
chemical reactions or heat transfer within or in an immediate vicinity of the system. CFD
applications include pressure drop, flow straitening and mixing evaluation, various
nozzle (s) or injector (s) designs in an open pipe, duct or inside of a confined vessel.
his technique also
helps to evaluate Fluid Patterns for SNCR/SCR applications or while combining the Low NOx
and Staged Combustion Air technologies.
his tool could be used
as an excellent sales aid, helping in visualization of the impact of the gas distribution
and/or mixing devices, nozzles, injectors, etc. on very complex multi-phase fluid flows in
the combustion systems. The study results are usually presented in the multi-color
graphical form to help easy identify flows and mixing patterns.
