CoMFRE jet atomization project captures unseen physics

Over the past four years, Kumar Saurabh, a graduate student in mechanical engineering, focused on developing new jet atomization algorithms to accurately capture the droplet composition and necessary physics. Existing methods based on adaptive dynamic networks become computationally intractable when these multi-scale phenomena are captured.

“This project gives you a new set of algorithms that people can use to simulate polyphase flow and break down the invisible physics that you can’t capture with just experiments,” Saurab said.

The new SORAP algorithm adapts the background network size depending on the background regions of interest (threads/leaves/drops) and finds a balance between computational cost and physics of interest; This is an important consideration in simulating complex phenomena in a reasonable amount of time, he said.

Saurabh collaborated closely with Makrand Ajay Khanuel (21 Ph.D. in mechanical engineering and applied mathematics), now a postdoctoral researcher at Stanford University, is on the project, among others. Baskar GanapathysubramanianAnd the Joseph C and Elizabeth A. Anderlik is Professor of Engineering, Director of the Artificial Intelligence Institute for Resilient Agriculture, Professor of Mechanical Engineering, and is the leader of Saurab’s research group.

Saurabh said he felt lucky to have such supportive guidance from Ganapathi Subramanian and Adarsh ​​Krishnamurthy, Associate Professor of Mechanical Engineering, for his interest in developing algorithms to solve challenging scientific problems. He felt fortunate to work with some of the brightest minds on his journey to develop new algorithms and ways to capture unseen physics.

Besides hearing about Iowa State University’s prestigious mechanical engineering program, being part of the Ganapathysubramanian research group was the driving force for Saubrah’s decision to apply to Iowa State. He knew that he would gain valuable experience in both the computational and applied side.

“Bashkar is one of the best mentors anyone in graduate school can get,” Sobra said. “He talks about new and innovative ideas and pushes his students to do things they haven’t done before.”

Through CoMFRE, Saurabh He also found opportunities to meet other professional professors who provide great guidance towards solutions.

“Studying in Iowa is a wonderful experience where I can do what I love. I have worked with some of the biggest machines, explored different fields and developed skills in many areas that interest me,” Saurabh said. “I couldn’t ask for a better place to work with modern engineering.” And overstepping my bounds.”
