SCoReT: Super-Resolution Compression and Reconstruction of Turbulent Flows
Royyuru Sai Prasanna Gangadhar, Shishir Srivastava, Nagabhushana Rao Vadlamani +1
High-fidelity simulations of the Navier--Stokes equations (NSE) generate massive amounts of data, motivating the need for efficient compression and reconstruction strategies for tu…
Acoustic Loading Beneath High-Speed Flow Over a Compression Ramp at Different Angles
Ritu Raj Kumar, Nagabhushana Rao Vadlamani, Amareshwara Sainadh Chamarthi
Large-eddy simulations are performed to characterize the pressure fluctuations beneath a hypersonic boundary layer approaching a compression corner. The simulations are carried out…
On the governing mechanism of unsteadiness in bow shock-induced three-dimensional separation
S. Vayala, K. Ramachandra, K. Abhishek +2
We investigate the driving mechanism of low-frequency unsteadiness in bow shock-turbulent boundary layer interactions due to protuberances. Wind tunnel experiments are conducted at…
Accuracy and scalability of asynchronous compressible flow solver for transitional flows
Aswin Kumar Arumugam, Shubham Kumar Goswami, Nagabhushana Rao Vadlamani +1
To overcome the communication bottlenecks observed in state-of-the-art parallel time-dependent flow solvers at extreme scales, an asynchronous computing approach that relaxes commu…
