Abstract: The study group was tasked to investigate: 1. how gas ows through irregularly shaped particles, and whether the Kozeny-Carman equation (relating the Kozeny-Carman constant K, porosity \phi and specific surface area S_k), could be improved to extend the usual spherical particle geometries to account for cylindrical, tetrahedral, ellipsoid and rhombic particle geometries; 2. the critical pressure for the collapse of bed; 3. the rate of reaction and build up in pressure in energetic porous beds; 4. "chuffing" - a periodic phenomenon observed in the later stages of some experiments, thought to be due to incomplete ignition of reactants in the initial phase of the reaction.
