2.5 Constant concentration contour curves about the sink are shown labeled for the various dimensionless concentration values u ( = cD / a2σ 2 ) . The diffusion-controlled sink ( 1 0 → λ ) is the smaller of the two spheres near the center of the figure, the larger source appears partially at the right. The x1, y1 grid refers to the coordinates from the center of the sink of radius 1 1 = a , and the source has a radius a 10 . The center-to-center sink-source 2 = −1 separation d( a1 + a2 ) = 1. 20 is taken to be slightly larger than the distance for the maximum reaction probability………..………….…. 47 2.6 Constant concentration contour curves about the sink are shown labeled for the various dimensionless concentration values u ( = cD / a2σ 2 ) .
