Abstract

The paper presents the thermographic studies of unsteady heat fluxes behind a plane shock wave in rectangular 24x48 mm tube test section. Consecutive panoramic visualization plots on streamlined walls after interaction with obstacle fixed channel wall are obtained. duration recorded thermal processes is up to 40 milliseconds passage. heating and cooling chamber by supersonic flow visualized usi...

with speed increasing in high-speed trains, due to limitations of other types of brakes, aerodynamic brake has become an important braking method. in this task to make better use of brake’s panel different configurations are examined and the best panel shape which provides the reasonable drag coefficient is introduced. the results of simulations are carried out with the computational fluid dyna...
