Sandipan K. Das, Ph.D.

Senior Consultant

Dr. Das is a senior consultant with Engineering Systems Inc. (ESi). Over the course of his professional career, he has provided solutions for multi-physics fluid dynamics problems cutting against different industry segments like power, automotive, HVAC, chemical, environmental and aerospace by developing and applying Computational Fluid Dynamics (CFD) tools. Specifically, he has more than a decade of experience working exclusively in the oil and gas industry.

Dr. Das has worked both as a technical consultant addressing various troubleshooting issues in industrial sites worldwide and as a researcher focusing on long term scientific challenges faced by the industry. In the process, he has dealt with a wide variety of physical problems like multiphase flows in separator vessels, mixing in various tanks, gas-solid flows in regenerators, atmospheric dispersion of pollutants, electrochemistry modeling in molten carbonate fuel cells, low Reynolds Number flows in carbon capture devices etc. On the other hand, he has also contributed significantly to the theoretical development on various fundamental aspects of diverse physical processes like turbulence modeling, multiphase flows, multicomponent diffusion in porous media, numerical methods etc. He has published widely in reputed academic journals and his inventions have resulted in the grant of a number of US patents.
