Aerospace article that he wrote was " Sustainable
(Green) Aviation - Challenges and Opportunities. "
Agarwal has also been deeply involved with SAE
going all the way back to the 1990s and all the way
across the globe, serving the organization at the
section, national, and international levels.
" SAE has been very supportive of my activities and
has provided me with an opportunity to participate in
many important committees and honored me with
many awards, " he told Update. " It has contributed a
great deal in my professional development,
recognition, and international visibility. "
Update asked Agarwal to describe some of the
work he is currently doing. In response, he said:
" I am very proud of my recent work in turbulence
modeling funded by NASA. I have developed three
turbulent and transitional flow models, which I call
the Wray-Agarwal (WA) family of models. These are
listed on the prestigious NASA Turbulence Modeling
Resource (TMR) website. Almost all fluid flows are
turbulent. Their numerical simulation requires the
solution of Reynolds-Averaged Navier-Stokes (RANS)
equations with a turbulence model.
The WA family of turbulence models are
increasingly being used worldwide for a wide variety
of complex 3D industrial applications. Since it is a
relatively new turbulence model proposed after 30
years in the literature, it will take some time for it to
go into commercial CFD codes and get more
widespead use. But I am very optimistic. The link for a
description of the model can be found here.
Agarwal is also busy in the area of hydrogenpowered
transonic commercial aircraft. " This work
addresses one of the ideas/approaches for almost
emissions-free aviation by 2050 for medium and longrange
commercial aircraft, " he said.
