Abstract : Most conventional detonating explosives produce a similar type of blast wave because their energy is released much more rapidly than the time required to form the blast wave. (In a detonating explosion where the reaction front moves at supersonic speeds, the surrounding air is not 'aware' of the release of the energy until the blast wave is completely formed.) In what is termed a 'nonideal' explosion, the rate of energy release is subsonic and the surrounding medium (air) is indeed aware that energy is being liberated. Attempt is made to determine how much of the energy from such an explosion appears in the subsequent blast wave. To simulate a nonideal explosion, a mixture of hydrogen (H2) and oxygen (O2) is burned and the manner of formation of the blast wave and its strength are determined. The data are used to test the validity of the Brinkley model for nonideal explosions. (Author)
