The most physically consistent approach to model non-equilibrium flows relies on the direct numerical solution of the master equation5,6,9,10,11,12,13, whereby all the relevant spatial and temporal scales resulting from chemical and radiative processes are accounted for. Indeed, the availability of...

Non-equilibrium flows of N 2/N and O 2/O mixtures with dissociation, recombination and excitation of vibrational levels are considered. Vibrational distributions, gas dynamic parameters as well as the transport coefficients and total energy flux are computed along the nozzle axis using four ...
In that particular case, this led to some later work on preferential flows (e.g., Watson and Luxmoore, 1986); in many other cases, such values were simply excluded as "outliers" or anomalies. Such was the power of the B-R paradigm....
From a practical standpoint, nonequilibrium and separating flows are perhaps the most important flows, since they are so often encountered in the design of diffusers and lifting surfaces. We now present the results for a flow of this type and consider an airfoil-like body that has both favorabl...
The non-equilibrium condition is responsible for a richer mean-field dynamics, such as condensation in excited states, topological lasing, outward flows in localized condensates, spiralling condensate phases around quantized vortices, diffusive Goldstone modes and generalized Landau criteria for superfluidity...
The predictions of the multiple-regime flows from continuum regime to free molecular regime are crucial for the aerodynamic design in a large number of engineering applications, such as the near-space craft, the ultra-low orbit spacecraft and the micro- electro-mechanical systems (MEMS). Since ...
