TL;DR: In this paper, a review of the problems of a continuum flow regime which cannot be solved without regarding the gas as a collection of molecules is presented, and some of these problems are important for aerothermodynamics.

TL;DR: In this paper, the authors describe some recent developments in the application of unstructured mesh, solution-adaptive methods to the solution of the Navier-Stokes equations in turbomachinery flows.

TL;DR: The free piston shock tunnel has shown itself to be uniquely capable of adequately simulating real gas effects and has been successfully operating in Australia for more than two decades as mentioned in this paper, which is in the light of these events that this paper discusses the development, performance and capabilities of Free Parnter shock tunnels.

TL;DR: In this paper, an empirical law is proposed to predict the normal force fluctuations on aerofoils with trailing-edge separations at subsonic speeds from CL-α curves, based on an equivalent separation position as deduced from the Kirchoff free-streamline flow for flat plates.

TL;DR: In this article, a criterion based on how the speed of sound varies with density is suggested for distinguishing between the two foam regimes, and practical applications of these properties are discussed, including the simulation of high speed flows.

TL;DR: In this paper, a graphical method for optimization of endurance cruise is presented, based on the minimum principle and the method of multiple shooting is presented for constructing a solution for periodic optimal endurance cruise.

TL;DR: In this article, the main advantages of the cryogenic option are highlighted which led to this type being adopted for transonic testing, together with brief descriptions of several of the more major tunnel projects.

TL;DR: A review of recent developments in the field of flow visualization, revisits the many possible pitfalls in interpreting the results and illustrates the splendor of fluids in motion can be found in this paper.
