摘要

目前冲击波超压测试常采用笔式、杆式和盘式3种不同形状的测压装置,而它们对冲击波测试特性的影响不尽相同。针对于此,文中使用Fluent软件模拟仿真了这3种测压装置在激波管内的气体流场,研究其对冲击波测试特性的影响程度,并通过相关冲击波超压实测试验来验证仿真结果。得出以下结论:试验结果与仿真结果一致,笔式测压装置和盘式测压装置均会对冲击波流场膨胀过程产生一定的阻碍作用,但笔式测压装置的阻碍作用小。

Abstract

Pen, rod and disc are three different shapes of pressure measuring device used in current shock wave overpressure test, and different shapes have different effects on shock wave test characteristics. For this, the paper uses the software Fluent to simulate the gas flow field in the shock tube with the three shapes: pen, rod and disc to study the influence on shock wave test characteristics. The simulation results are verified by the relevant shock wave overpressure test. It is concluded that the test results are consistent with the simulation results. Both the pen-type and the disc-type pressure measuring devices have a certain hindrance to the expansion process of shock wave flow field, but the hindrance of the pen-type is small.

Key words： shock wave; shape of pressure measuring device; shock tube; numerical simulation
