Resolvent analysis to inform viscoelastic coatings for turbulent drag reduction
Soumen Chakravarty, Venkat Narayanaswamy
Viscoelastic compliant coatings offer a passive route to modify wall-bounded turbulence; however, their effectiveness for drag reduction remains unresolved. We perform resolvent an…
Adaptive Thrust Regulation in Solid-fuel Ramjet with Variable Geometry Inlet
Parham Oveissi, Ryan DeBoskey, Venkateswaran Narayanaswamy +1
This paper presents the application of a novel data-driven adaptive control technique, dynamic mode adaptive control (DMAC), to regulate thrust in a solid-fuel ramjet (SFRJ). A qua…
An In-situ Solid Fuel Ramjet Thrust Monitoring and Regulation Framework Using Neural Networks and Adaptive Control
Ryan DeBoskey, Parham Oveissi, Venkat Narayanaswamy +1
Controlling the complex combustion dynamics within solid fuel ramjets (SFRJs) remains a critical challenge limiting deployment at scale. This paper proposes the use of a neural net…
High fidelity simulations of unstart phenomena in a scramjet inlet due to angle of attack
Jeremy Redding, Emma Cavanaugh, Luis Bravo +2
This work investigates the unsteady behavior of unstart phenomena within a scramjet inlet using advanced computational techniques. Scramjets and ramjets, with their reliance on inl…
