FIGURE 13.4 Comparison of particle properties for a simple model with rectilinear and curvilinear coagulation kernels. Calculations use a simple sectional model55 for 50 m mixed layer thickness, algal radius = 5 ^m, specific growth rate ^ = 0.5 per day, shear y = 0.1 sec-1, and stickiness a = 1. Solid line indicates a rectilinear kernel; dashed line indicates a curvilinear kernel. (a) Volumetric concentration. Lines with asterisks indicate total particle concentrations; plain lines indicate the volumetric concentration of single algae; the critical concentration is indicated with the dotted horizontal line. (b) Total particle flux at base of mixed layer. (c) Average particle velocity = total flux/total particle concentration.
