a1.gif (929 bytes)llied 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-Best viewed with the free Acrobat Reader version 4.0 or laterDownload Adobe Acrobat Reader Now). If it is a complex problem, and it involves fluids and complex environments (temp, pressure, velocity, etc.) we can model it. Our staff is led by experienced analysts with many years in the CFD consulting business.

Our main analysis tools are well established commercial CFD software packages. 

t1.gif (918 bytes)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.

t1.gif (918 bytes)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.

t1.gif (918 bytes)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.
