The development of disturbances in the boundary-layer transition (BoLT) flight experiment flowfield is investigated using a recently developed “quiet direct numerical simulation (DNS)” approach. By...

A Bayesian predictive inference approach, for the development of classical sliding window detection processes, is the focus of this article. It will be demonstrated that this methodology can produce such detectors with the constant false alarm rate (

A computational approach is developed to simulate high-enthalpy shock propagation under strong nonequilibrium conditions, such as reentry experiments at NASA’s Electric Arc Shock Tube (EAST) facili...

We study a class of chemically reacting, spatially evolving, subsonic mixing layers via large eddy simulations (LES). A primary goal is to assess the inflow conditions, numerical methods, and physical models requirement to reproduce experimental resu

We employ global input-output analysis to quantify amplification of exogenous disturbances in compressible boundary layer flows. Using the spatial structure of the dominant response to time-periodic inputs, we explain the origin of steady reattachmen

Analysis of high-resolution X-band maritime surveillance radar clutter has demonstrated the validity of the Pareto Type II fit to such data. Based upon this, and the fact that in some cases the Pareto Type II model can be approximated by a Pareto Typ

We study and compare instability mechanisms of a Mach 5.65 laminar boundary layer tripped by an isolated diamond-shaped trip and by an array of diamond-shaped trips using direct numerical simulations. A low-Reynolds-number experiment, consisting of t

Setting thresholds for sliding window noncoherent detection processes is extremely difficult in the presence of a correlated clutter range profile. This is certainly the case when attempting to apply a trimmed sum of order statistics as the measureme

A number of recent studies have shown that the Pareto distribution is a suitable alternative to the K-distributional model, for X-band maritime surveillance radar clutter. As such there has been interest in the development of non-coherent sliding win
