Work Packages

Work Package 1 – Multisource database development for flow control

Task 1.1 – Generation of numerical and experimental flow data

Objectives Produce high-quality flow data across various configurations of curved walls both in the absence or presence of Görtler instabilities.
Deliverables Comprehensive database of velocity fields, wall pressure distributions, and derived quantities (vorticity, Q-criterion, etc).

Task 1.2 – Development of estimators for real-time flow predictions

Objectives Develop robust estimators predicting the evolution of flow variables of interest from limited measurements accessible in practical applications.
Deliverables Suite of validated estimators for real-time flow predictive with quantified uncertainty, implemented as software modules compatible with control applications.

Task 1.3 – Database integration and management

Objectives Integrate data from multiple sources into a structured, accessible database system.
Deliverables Integrated database platform with search capabilities and documented APIs for data retrieval along with a comprehensive report on data quality assessment.

Work Package 2 – Defining a dynamically-constrained solution space

Task 2.1 – Reduced the action space: perturbation identification and instability characterization

Objectives Modal and non-modal stability analyses of Görtler vortices on concave walls.
Deliverables Provide a better understanding of the physical mechanisms responsible for the appearance of centrifugal instabilities and data to feed and guide the learning methods.

Task 2.2 – Reduced the state-space: building reduced-order models

Objectives Develop reduced-order models capturing the key dynamics of the flow to enable real-time implementation of control strategies.
Deliverables Suite of validated reduced-order models with quantified accuracy metrics, comparison reports against full-order simulations, and software implementation for integration with control algorithms.

Task 2.3 – Coupling stability analysis with machine learning

Objectives Develop a novel integration framework combining physical insights from stability analyses with machine learning approaches to create physics-informed dictionaries for symbolic regression.
Deliverables Physics-informed dictionaries for symbolic regression, formal specifications for the dynamically-constrained solution space, and documentation of the methodological framework for integrating stability analysis with machine learning.

Work Package 3 – Generalizable control law leveraging secondary flow instabilities

Task 3.1 – Design of interpretable control laws

Objectives Develop interpretable control lwas to manipulate Görtler vortices for specific flow configurations, enhancing mixing momentum.
Deliverables LIbrary of interpretable control laws for different but limited flow configurations, along with detailed performance analyses.

Task 3.2 – Development of adaptive control framework

Objectives Extend the applicability of the control laws beyond their design conditions through complementary approaches: ROM with embedded control effects, and data assimilation and reinforcement learning for real-time applications.
Deliverables Reduced-order models with embedded control effects for selected flow scenarios, along with data assimilation and reinforcement learning frameworks for adaptive control implementations.
