Abstract
In this paper, we provide the experimental evidence of a free-standing conical shock and the compressive confocal characteristics region in the Busemann intake flow. The experiments are carried out in the DRDC Trisonic Wind Tunnel at freestream Mach number 3.0 with a Busemann ring model. The Taylor-McColl equations are integrated to obtain the Busemann streamline and hence the inner surface of the Busemann ring. The CFD analysis of the flow using a locally adaptive unstructured Euler finite-volume code is in agreement with the experiments.
期刊介绍：
Shock Waves provides a forum for presenting and discussing new results in all fields where shock and detonation phenomena play a role. The journal addresses physicists, engineers and applied mathematicians working on theoretical, experimental or numerical issues, including diagnostics and flow visualization.
The research fields considered include, but are not limited to, aero- and gas dynamics, acoustics, physical chemistry, condensed matter and plasmas, with applications encompassing materials sciences, space sciences, geosciences, life sciences and medicine.
Of particular interest are contributions which provide insights into fundamental aspects of the techniques that are relevant to more than one specific research community.
The journal publishes scholarly research papers, invited review articles and short notes, as well as comments on papers already published in this journal. Occasionally concise meeting reports of interest to the Shock Waves community are published.
