In fluid dynamics, predicting and characterizing bifurcations, from the onset of unsteadiness to the transition to turbulence, is of critical importance for both academic and industrial …
Microfluidic experiments and discrete particle simulations using the lattice-Boltzmann method are used to study interactions of finite size hard spheres and vortical flow inside …
The study of the stability of a dynamical system described by a set of partial differential equations (PDEs) requires the computation of unstable states as the control parameter …

The adjoint method has been used in the indoor environment for more than ten years, but it has not been widely used up to now. This paper describes the current state of the adjoint …
The present work investigates sidewall effects on the characteristics of three-dimensional (3- D) compressible flows over a rectangular cavity with aspect ratios of L/D= 6 and W/D= 2 at R …

The Rossiter modes of an open cavity were studied using bi-global linear analysis, local instability analysis and nonlinear numerical simulations. Rossiter modes are normally seen …
The present work demonstrates the use of a resolvent analysis to obtain physical insights for open-cavity flows. A resolvent analysis identifies the flow response to harmonic forcing …
In this work, the analytical derivation and the computer implementation of the adjoint method are described. The adjoint method can be effectively used for solving the optimal control …
