Cluster regression model for control of nonlinear dynamics
Nitish Arya, Aditya G. Nair
In the realm of big data, discerning patterns in nonlinear systems affected by external control inputs is increasingly challenging. Our approach blends the coarse-graining strength…
Network-theoretic modeling of fluid-structure interactions
Aditya G. Nair, Samuel B. Douglass, Nitish Arya
The coupling interactions between deformable structures and unsteady fluid flows occur across a wide range of spatial and temporal scales in many engineering applications. These fl…
Acoustic characteristics of supersonic planar impinging jets
Nitish Arya, Ashoke De
The present work aims to study the tonal and broadband noise associated with a supersonic planar jet impinging on a flat plate. Five different cases are considered corresponding to…
Effect of vortex and entropy sources in sound generation for compressible cavity flow
Nitish Arya, Ashoke De
The present study reports the effect of different source terms on the near and far-field acoustic characteristics of compressible flow over a rectangular cavity using hybrid comput…
Characterization of turbulent supersonic flow over a backward facing step through POD
R. K. Soni, N. Arya, Ashoke De
The present work reports on the flow physics of turbulent supersonic flow over backward facing step (BFS) at Mach 2 using LES methodology where the dynamic Smagorinsky model is use…
Effect of grid sensitivity on the performance of wall adapting SGS models for LES of swirling and separating reattaching flows
Nitish Arya, Ashoke De
The present study assesses the performance of the Wall Adapting SGS models along with the Dynamic Smagorinsky model for flows involving separation, reattachment and swirl. Due to t…
Investigation of Flow Characteristics inside a Dual Bell Nozzle with and without Film Cooling
Mayank Verma, Nitish Arya, Ashoke De
In this study, we perform a two-dimensional axisymmetric simulation to assess the flow characteristics and understand the film cooling process in a dual bell nozzle. The secondary…
Modal Decomposition of Turbulent Supersonic Cavity
Rahul Kumar Soni, Nitish Arya, Ashoke De
Self-sustained oscillation in Mach 3 supersonic cavity with a length-to-depth ratio of 3 is investigated using wall modeled Large Eddy Simulation (LES) methodology for ReD = 3.39*1…
