“…An interesting special case is the evaporation and subsequent combustion of a spray of finely dispersed liquid fuel droplets, a process in which the transfer of both heat and mass is involved. [1][2][3][4] In systems where multiple stationary reaction centres are in close proximity to each other, the reactive centres compete for the diffusing molecular agent. As a result, the reaction rate per site is lower than in the case of single sites.…”

The subject of this paper is competitive effects between multiple reaction sinks. A theory based on off-center monopoles is developed for the steady-state diffusion equation and for the convection-diffusion equation with a constant flow field. The dipolar approximation for the diffusion equation with two equal reaction centres is compared with the exact solution. The former turns out to be remarkably accurate, even for two touching spheres. Numerical evidence is presented to show that the same holds for larger clusters (with more than two spheres). The theory is extended to the convection-diffusion equation with a constant flow field. As one increases the convective velocity, the competitive effects between the reactive centres gradually become less significant. This is demonstrated for a number of cluster configurations. At high flow velocities, the current methodology breaks down. Fixing this problem will be the subject of future research. The current method is useful as an easy-to-use tool for the calibration of other more complicated models in mass and/or heat transfer.
