Beyond the Mean-flow: A Spectral-Dynamic Approach to Unraveling the Physics of Droplet Capture in Fog Harvesting Meshes
Pradyumna Das, Ranjan Ganguly, Ashoke De
Fog harvesting efficiency with mesh collectors is governed by complex interactions between droplet inertia and geometry-induced flow structures. Although previous studies have prim…
Data-driven stability analysis in a multi-element supercritical Liquid Oxygen-methane combustor
Arijit Bhattacharya, Abhishek Sharma, Ashoke De
Thermoacoustic instability (TAI) is a pressing problem in rocket combustors. TAI can cause significant damage to a combustor, resulting in mission failure. Therefore, stability ana…
Impact of Fuel Injection Temperature Dynamics on the Stability of Liquid Oxygen-Methane Supercritical Combustion
Abhishek Sharma, Ashoke De, S. Sunil Kumar
A crucial factor in the stability of high-pressure rocket-scale combustors is the temperature at which fuel is injected. This study investigates its effect on the stability of supe…
Flow Dynamics of the Transversely Oscillating Tapered Circular Cylinder under Vortex-Induced Vibrations at low Reynolds number
Mayank Verma, Ashoke De
This study numerically investigates the influence of the taper on the flow-induced vibrations of an elastically mounted circular cylinder under Vortex-induced vibrations. The dynam…
