Abstract:

THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP AN IMPROVED DIFFERENTIAL PRESSURE GAGE FOR DETERMINING DYNAMIC PRESSURE WITHIN BLAST AND SHOCK WAVE FLOWS WHERE THE FLOWS ARE SUBSONIC. DERIVATION OF DYNAMIC PRESSURE FROM A MEASUREMENT OF THE DIFFERENCE BETWEEN STAGNATION PRESSURE AND SIDE-ON OR STATIC PRESSURE REQUIRES USE OF THE SIDE-ON PRESSURE RECORD TO CORRECT FOR COMPRESSIBILITY EFFECTS. CURRENTLY THE SIDE-ON PRESSURE WAVEFORM MUST BE MEASURED BY A SEPARATE GAGE LOCATED APART FROM THE DIFFERENTIAL PRESSURE GAGE. THIS WAVEFORM MAY DIFFER FROM THAT OCCURRING AT THE DIFFERENTIAL PRESSURE GAGE LOCATION. UNDER THIS PROJECT, THE DIFFERENTIAL PRESSURE GAGE PROBE WILL BE MODIFIED TO ADD A GAGE TO MEASURE THE SIDE-ON PRESSURE IN ADDITION TO THE DIFFERENTIAL PRESSURE. THIS MODIFIED PROBE WILL BE EVALUATED IN SHOCK TUBE TESTS.
