Narrative: It is proposed to study coagulation of fine particle                 aerosols using static and dynamic light scattering and electron                 micrography inspection.  The goals are:                                                                                                                                                  l.   To determine the applicability of                                               the fractal concept to describe                                                 aerosol particle morphology and how                                             this fractal morphology depends on                                              Knudsen number, particle                                                        interactions, and concurrent                                                    surface growth.                                                                                                                                            2.   To test temporal scaling of the                                                 coagulative growth of aerosols in                                               the entire Knudsen regime and                                                   determine the dependence of the                                                 coagulation kernel homogeneity and                                              dynamic fractal dimension on                                                    Knudsen number, particle                                                        interactions, and concurrent                                                    surface growth.                                                             3.   To measure the approach of an                                                  arbitrary aerosol particle size                                                 distribution to the self-preserving                                             form and study the effects of                                                   fractal morphology on the                                                       measurement.                                                                                                                                               4.   To measure the rate of coagulation                                              in the intermediate Knudsen regime                                              in both liquid and solid particle                                               aerosols.                                                                                                                                                  5.   To characterize the phenomenon of                                               aerosol clumping and determine its                                              effect on coagulative growth.                                                                                                     Aerosols will be created from either oil droplets (DOP) or solids               (NaCl, Ag) and soot from premixed flames.  Sizes will be in the                 5-100 nm range before coagulation.  An understanding of aerosol                 coagulation, its rate and temporal evolution, and its effect on                 the resultant cluster morphology will help our fundamental                      understanding of aerosols and the coagulative process.
