  We introduce a simplified model of physiological coughing or sneezing, in the
form of a thin liquid layer subject to a rapid (30 m/s) air stream. The setup
is simulated using the Volume-Of-Fluid method with octree mesh adaptation, the
latter allowing grid sizes small enough to capture the Kolmogorov length scale.
The results confirm the trend to an intermediate distribution between a
Log-Normal and a Pareto distribution $P(d) \propto d^{-3.3}$ for the
distribution of droplet sizes in agreement with a previous re-analysis of
experimental results by one of the authors. The mechanism of atomisation does
not differ qualitatively from the multiphase mixing layer experiments and
simulations. No mechanism for a bimodal distribution, also sometimes observed,
is evidenced in these simulations.
