Objective early identification of kinematic instabilities in shear flows
Bjoern F. Klose, Mattia Serra, Gustaaf B. Jacobs
A kinematic approach for the identification of flow instabilities is proposed. By defining a flow instability in the Lagrangian frame as the increased folding of lines of fluid par…
Assessing Standard and Kinetic Energy Conserving Discontinuous Galerkin Formulations for Marginally Resolved Navier-Stokes Flows
B. F. Klose, G. B. Jacobs, D. A Kopriva
The robustness and accuracy of marginally resolved discontinuous Galerkin spectral element computations are evaluated for the standard formulation and a kinetic energy conserving s…
An explicit semi-Lagrangian, spectral method for solution of Lagrangian transport equations in Eulerian-Lagrangian formulations
Hareshram Natarajan, Gustaaf B. Jacobs
An explicit high order semi-Lagrangian method is developed for solving Lagrangian transport equations in Eulerian-Lagrangian formulations. To ensure a semi-Lagrangian approximation…
Data-Driven Selection of Actuators for Optimal Control of Airfoil Separation
Debraj Bhattacharjee, Bjoern Klose, Gustaaf B. Jacobs +1
We present a systematic approach for determining the optimal actuator location for separation control from input-output response data, gathered from numerical simulations or physic…
The Kinematics of Lagrangian Flow Separation in External Aerodynamics
Bjoern F. Klose, Mattia Serra, Gustaaf B. Jacobs
Kinematic aspects of flow separation in external aerodynamics are investigated in the Lagrangian frame. Specifically, the initial motion of upwelling fluid material from the wall i…
Method of Distributions for Systems with Stochastic Forcing
Rik J. L. Rutjens, Gustaaf B. Jacobs, Daniel M. Tartakovsky
The method of distributions is developed for systems that are governed by hyperbolic conservation laws with stochastic forcing. The method yields a deterministic equation for the c…
