Shock Regime Thermoelectric Effect in Detonation

Detonation, Shock Regime Thermoelectric Effect in. When a shock wave crosses the junction surface of two different metals, there appears between the uncompressed extremities of the metals a difference in potential, the magnitude of which is dependent on the amplitude of the shock wave the nature of the metals. This effect had been first noted in 1959 during the investigation of a thermal elec detector for the recording of temp at the shock front. 

The adiabatic compression of the metal in the shock gives rise to an increase in temp. The experimental study of the electrical response of thermocouples made with different metals, when put into shock loaded metallic samples, s.howed that a) they behave like static thermocouples and b) the response seems to increase with pressure up to l600kilobars and is of such magnitude that any classical interpretation appears impossible (Ref)
