Investigation of a Sharp 10° Cone in a Ludwieg Tube
The objectives of this study were (i) to create a unique test case of an unsteady flow around a cone in a Ludwieg tube for the purpose of validating computational codes; (ii) to test a new method for determining non-stationary aerodynamic loads using a strain-gauge balance; and (iii) to test a new method for determining unsteady pressure using a Pitot-Prandtl-type probe with a cavity between the sensor and the flow. The results of testing of a 10° cone in the TsAGI short-duration UT-1M Ludwieg-type tube at Mach number M = 6 are presented. During the runs, the following parameters were measured simultaneously: non-stationary aerodynamic loads using an internal six-component strain-gauge balance, dynamic behavior of the cone and balance using three-axis accelerometers, unsteady pressure on the cone surface, total and static pressure using a Pitot-Prandtl-type probe, cone surface temperature using a temperature sensitive paint, flow parameter fluctuations on the cone surface using a constant voltage film thermoanemometer. In some tests, the flow was visualized using the Schlieren method. Before the tests, numerical calculations of the flow around the cone in the facility were performed with the EWT-TsAGI software package to select the location of the oversized cone and the Pitot-Prandtl-type probe in the test section. The conducted studies confirmed the applicability of the new methods for measuring non-stationary forces and unsteady pressure in short-duration wind tunnels.
期刊介绍:
Flow, Turbulence and Combustion provides a global forum for the publication of original and innovative research results that contribute to the solution of fundamental and applied problems encountered in single-phase, multi-phase and reacting flows, in both idealized and real systems. The scope of coverage encompasses topics in fluid dynamics, scalar transport, multi-physics interactions and flow control. From time to time the journal publishes Special or Theme Issues featuring invited articles.
Contributions may report research that falls within the broad spectrum of analytical, computational and experimental methods. This includes research conducted in academia, industry and a variety of environmental and geophysical sectors. Turbulence, transition and associated phenomena are expected to play a significant role in the majority of studies reported, although non-turbulent flows, typical of those in micro-devices, would be regarded as falling within the scope covered. The emphasis is on originality, timeliness, quality and thematic fit, as exemplified by the title of the journal and the qualifications described above. Relevance to real-world problems and industrial applications are regarded as strengths.
