Hugoniot shock
WebAs implied before, the shock Hugoniot curve must pass through A. For different values of q, one obtains a whole family of Hugoniot curves. [Pg.271] When q = 0, the Hugoniot curve represents an adiabatic shock. Point 1 (Pi, p ) is then on the curve and Y and J are 1. Then [ (l/pt) - (Ilp2) = 0, and the classical result of the shock theory is ... Web28 mrt. 2006 · Properties of some Hugoniot curves associated with shock instability.
