| Popis: | 97 The purpose of this research by using the technique of color schlieren is to set up a suitable facility which could be used to study the experiment based on the theory of a weak blast wave; this weak blast wave is generated by a high voltage spark.According to the visualization and the measurement results of the weak blast wave which was generated by both two hundred thousand volts and three hundred thousand volts electricity and it was observed that the image quality is much batter than the shadowgraph method. In this facility the available range of time for visualizing and measuring the weak blast wave in the experiment is of three micro second to forty micro second. With the changing of the discharge electric voltage range, the radius of weak blast wave is also changed accordingly.It indicates that the energy of the weak blast wave is directly related to the voltage of the sparking. |
