(BQ) Part 2 book "Methods for the calculation of physical effects" has contents: Vapour cloud explosion, heat flux from fires, ruptures of vessels, interfacing of models. | Chapter 5 Vapour cloud explosions W.P.M. Mercx, A.C. van den Berg 5.1 CPR 14E Chapter 5 of the ‘Yellow Book’ Modifications to Chapter 5 (Vapour cloud explosions) with respect to the first print (1997) Numerous modifications were made concerning typographical errors. A list is given below for the pages on which errors have been corrected. At page 5.24: the declaration of variable EmTNT (TNT blast energy) is corrected, and values currently in use for this variable are added. In the calculation examples of the application of selected methods: calculation examples A lot of numbers are refined, and values are more accurately read from plots and figures. The values of Tables 5.6, 5.7A, 5.7B have been replaced by refined values. 5.3 5.4 CPR 14E Chapter 5 of the ‘Yellow Book’ List of symbols Chapter 5 Af,rainout aa bf,rainout bi cp cs D1 Vgr Vo Vr Jet cross-section after flashing and rainout (5.10) Speed of sound in ambient air (5.4) Jet radius after flashing and rainout (5.10) Dimension of a box Specific heat at constant pressure Stoichiometric concentration (5.7) Smallest dimension of obstacle perpendicular to flame propagation direction Dimension of obstacle parallel to flame propagation direction Diameter of a cylinder Diameter of a sphere Total combustion energy (5.2) Combustion energy per unit mass (5.1) Combustion energy of fuel per unit mass (5.1) Combustion energy of TNT per unit mass (5.1) Combustion energy per unit volume (5.9) Positive side-on impulse of blast-wave (5.6) Overpressure in vapour cloud Peak side-on overpressure of blast-wave (5.3) Scaled peak side-on overpressure of blast-wave (5.3) Ambient pressure (5.2) Peak dynamic pressure in blast-wave (5.5) Scaled dynamic pressure in blast-wave (5.5) ‘Chapman-Jouguet’ peak detonation pressure ‘Von Neumann’ peak detonation pressure Mass quantity of flammable part of the cloud (5.7) Mass of fuel involved (5.1) Equivalent mass of TNT (5.1) Distance to explosion centre (5.2) Scaled distance .
