Hypersonic Flow-Field Measurements - Intrusive and Nonintrusive
Abstract
Flow-field measurement techniques that require a probe or other device to be inserted into the flow are classified as intrusive. In general, these intrusive techniques are currently viewed as inferior to the more popular nonintrusive techniques. However, it should be remembered that in general these intrusive techniques have evolved over several decades while the flow-field experience of nonintrusive techniques is relatively limited. Included in the intrusive classification are pitot tubes, total temperature probes, Mach/ angularity probes, static pressure devices, and others. For many years nonintrusive diagnostics have also been under development to meet the demands of hypersonic testing. Today, a large number of nonintrusive techniques at various levels of maturity and complexity are available for application. These techniques provide measurement of species number density, rotational and vibrational temperatures, static pressure, flow velocity, and visualization of flow structure.
