Query: An efficient cellular flow model for cohesive particle flocculation in
  turbulence   We propose a one-way coupled model that tracks individual primary particles
in a conceptually simple cellular flow setup to predict flocculation in
turbulence. This computationally efficient model accounts for Stokes drag,
lubrication, cohesive and direct contact forces on the primary spherical
particles and allows for a systematic simulation campaign that yields the
transient mean floc size as a function of the governing dimensionless
parameters. The simulations reproduce the growth of the cohesive flocs with
time, and the emergence of a log-normal equilibrium distribution governed by
the balance of aggregation and breakage. Flocculation proceeds most rapidly
when the Stokes number of the primary particles is \textit{O}(1). Results from
this simple computational model are consistent with experimental observations,
thus allowing us to propose a new analytical flocculation model that yields
improved agreement with experimental data, especially during the transient
stages.
