Bio: Dr. Akshai K. Runchal has over 60 years of experience in CFD and simulation of flow, heat
and mass transport processes in engineering and environmental sciences, He obtained his
Ph.D. in 1969 from Imperial College (London) under the guidance of Prof. D, B. Spalding.
He was a key member of the 3-person team led by Spalding that invented the Finite Volume
Method (FVM) of Fluid Dynamics (CFD) in mid 1960’s. He started his professional career
as a faculty at IIT Kanpur in 1969 and has also taught as regular or adjunct faculty at
Imperial College (London), University of California (Los Angeles), Cal Tech (Pasadena),
and Cal State (Northridge). In 1979, Dr. Runchal established the ACRi group of companies
(www.acricfd.com) that has offices in the USA, France and India.
For the past 60 years, Dr Runchal, has consulted extensively on projects related to flow,
heat and mass transfer, combustion, environmental impact, management of air, surface
and ground water resources, safe disposal of hazardous and nuclear waste, and, policy
and decision analysis. Dr. Runchal is a co-author of the first book ever published on
CFD. He is the author or co-author of 12 books and over 200 technical publications. He
is the principal author of the ANSWER®, PORFLOW®, TIDAL®, and RADM™ CFD Soft-ware Tools that are widely employed by commercial, academic, and R&D organizations.

Dr. Runchal has received professional honours and awards and has delivered keynote and
invited talks at more than 100 international conferences and seminars. In 2011, Dr. Runchal founded a non-profit CFD Virtual Reality Institute (www.CFDVRi.org) to further the
cause of CFD education, training, and R&D. He divides his time between Los Angeles and
McLeod Ganj and is actively engaged in promoting education, training, and R&D in CFD
and related disciplines
Affiliation: Technical Director of ACRi
Bio: Dr. M.M. Rao is a distinguished expert in Computational Fluid Dynamics (CFD) with over three decades of experience in research, software development, and consulting. He holds a B.Tech in Aerospace Engineering from IIT Madras (1988) and a Ph.D. from the University of Florida, Gainesville.
Dr. Rao began his career as a Project Engineer at ACRi’s Cincinnati office in 1996 and currently serves as the Technical Director of ACRi India. He has played a leading role in the development and implementation of unstructured mesh algorithms in the commercial finite volume CFD software ANSWER® as well as the implementation of advanced turbulence models including Reynolds Stress Models (RSM), non-linear k–ε models, RNG, and k–ω variants.
At ACRi, Dr. Rao leads R&D efforts involving CFD solver development (commercial codes: ANSWER, PORFLOW, TIDAL), adaptive mesh refinement, simulation of complex reacting flows, environmental flow modeling, and subsurface transport. His work extends to the numerical modeling of aerosol transport and dynamics, including applications in air quality.
He is also closely associated with the CFD Virtual Reality Institute (CFDVRi), where he guides education, training, and research activities. Dr. Rao is actively involved in extending CFD through Machine Learning techniques, with a particular focus on Physics-Informed Neural Networks (PINNs) to enhance predictive capabilities and computational efficiency.
Dr. Rao has co-authored the book Computational Fluid Dynamics with Moving Boundaries and has published extensively in reputed journals and conferences.
