Effects of Initial Temperature and Non-combustible Gases on Detonation Parameters

3 Effects of Initial Temperature and Non-combustible Gases on Detonation Parameters 

Let us study the effect of some non-combustible gasses on the detonation parameters. It is of practical interest to measure detonation parameters of H2 + air mixtures diluted with water steam or CO2. 

According to the results obtained in [8, 9] the detonation velocity at pressure Pq up to 10 MPa has a weak dependence on the initial temperature. As this takes place, the growth of the initial temperature leads to a noticeable decrease in the relative 

Cl - sound speed in the detonation products, a - cell size 

Overdriven detonation parameters of H2 + air mixtures are presented in Table 7.5 [10, 11]. Detonation parameters of hydrogen + nitrogen monoxide mixtures are given in Table 7.6 [10, 11].
