| Description | Journal: Journal of Physics A: General Physics The electric charging process, by bipolar ions, of nanometre-sized aerosol particles undergoing simultaneous Brownian coagulation is examined. Two approximate analytical models, valid for symmetrical charging and size-independent coagulation rate constant, are derived and compared with the numerical solution of the rigorous population balance equations. For each particle size, there exists an optimum mean aerosol residence time in the bipolar charging device for which the output concentration of charged particles is a maximum. The optimum residence time for the smallest particles is about one order of magnitude lower than the time required to attain the charge equilibrium state. In practical situations, the maximum attainable number concentration of charged particles is accordingly much lower than in equilibrium conditions. |
