Electromagnetic fields generated by turbulent air flow and shock waves

An electronic probe and a magnetic probe were used to study the electromagnetic fields generated by turbulent air flow in subsonic and supersonic wind tunnel tests. The electromagnetic field associated with the turbulent shear flow and shock waves may be due to the dynamic motion of H2and CO2 pooar molecules and the induction by polarization of dipole moments in N2, O2 and other molecules. The electronic and magnetic probes used respond only to AC signals and are, therefore, sensitive only to the dynamic motion of electric charges possibly associated with these dipoles.
