Ignition of metal powder by electrostatic discharge stimulation
… materials for which the kinetics of exothermic processes leading to ignition will be determined in separate experiments. The predictions will be validated experimentally using a standard ESD testing apparatus with additional optical sensors and electronic diagnostics.

Control strategies for exothermic batch and fed-batch processes A sub-optimal strategy is developed which combines fast response with a chosen control signal safety margin. Design procedures are described and results compared with conventional control.
… scope for improving the temperature control of exothermic processes. In this thesis, a sub-optimal control strategy is developed through utilizing the dynamic, simulation tool. This scheme is built around easily obtained knowledge of the system and still retains flexibility. It can be applied to …

Hydrodynamics, Mixing, and Mass Transfer in Bubble Columns with Internals
… chemical applications of bubble columns include exothermic processes and hence they require some means of heat removal to maintain a steady process. The most practical means for heat removal in these reactors is the utilization of vertical cooling internals since they provide high heat transfer …

Synthesis and characterization of mechanically alloyed aluminum-based compounds as high energy density materials
… measurements were performed to identify the processes affecting ignition for the prepared metastable powders. Al-Ti alloys were prepared with compositions ranging from Al_{0.95}Ti_{0.05} to Al_{0.75}Ti_{0.25}. Mechanically alloyed powders comprised solid solution of Ti and Al. Upon their …

Crystal growth and nucleation kinetics of diethylenetriammonium hexachlororhodate (III) salt
… and agglomeration, as defined in this work, were exothermic processes with activation energies of -192.9kJ/mol and -656.1kJ/mol respectively. Nucleation was found to be an endothermic process with an activation energy of 50.9kJ/mol in accord with the observed heat of crystallisation. No evidence …
