“…Theoretical and experimental determinations of fuel-air cloud detonations have been carried out by Fishburn (1976), Sichel andFoster (1979), andFishburn et al (1981). In this latter work it was demonstrated that despite having a heat of combustion about 10 times that of the heat of explosion of TNT the detonation of a hydrocarbon-air cloud can yield a ground blast e ect comparable to 20 times its fuel weight in TNT.…”

In the point explosion problem it is assumed that an instantaneous release of finite energy causing shock wave propagation in the ambient gas occurs at a space point.The results of the solution of the problem of such blasts are contained in [1][2][3][4].This point model is applied for the determination of shock wave parameters when the initial pressure in a sphere of finite radius exceeds the ambient air pressure by 2-3 orders of magnitude.The possibility of such a flow simulation at a certain distance from the charge is shown in papers [4,5] as applied to the blast of a charge of condensed explosive and in [6,8] as applied to the expansion of a finite volume of strongly compressed hot gas.In certain practical problems the initial pressure in a volume of finite dimensions exceeds atmospheric pressure by a factor 10-15 only. Such cases arise, for example, in the detonation of gaseous fuel---air mixtures. The present paper considers the problem of shock wave propagation in air, caused by explosion of gaseous charge of spherical or cylindrical shape.A numerical solution is obtained in a range of values of the specific energy of the charge characteristic for fuel--air detonation mixtures by means of the method of characteristics without secondary shock wave separation.The influence of the initial conditions of the gas charge explosion (specific energy, nature of initiation, and others) is investigated and compared with the point case with respect to the pressure difference across the shock wave and the positive overoressure pulse.
