An experimental set up was designed to separately test how sedimentation and convection driven flows affect the perikinetic coagulation process in a ground based experiment. The experiment showed that the sedimentation slightly accelerates the coagulation process and weak free convection driven flows do not noticeably contribute to coagulation for 2 μm particles' dispersion.
