In this manuscript we reply to the issues raised by G. Bagheri and C. Bonadonna in theircomment 2019JB017697. We reiterate our definition of particle Reynolds number, which is appropriatefor our data set of experimental measurements, and we show that the poor performance of Bagheri andBonadonna (2016, https://doi.org/10.1016/j.powtec.2016.06.015) model discussed in Dioguardi et al. (2018,https://doi.org/10.1002/2017JB014926) was mainly due to the typos in the equations presented in theiroriginal manuscript. We believe that the iterative methodology for calculating the drag coefficient is notstrictly necessary for our data set. In this reply, however, we also include results of the intercomparison studyamong different drag models using the iterative methodology. Results show that the performance of thedifferent drag models considered in the intercomparison study is not significantly affected by the employedmethodology (direct vs. iterative) and that, regardless the employed methodology and unlike what has beenstated in the comment 2019JB017697, our model has the best performance in reproducing theexperimentally measured terminal velocities.

Abstract

In this manuscript we reply to the issues raised by G. Bagheri and C. Bonadonna in theircomment 2019JB017697. We reiterate our definition of particle Reynolds number, which is appropriatefor our data set of experimental measurements, and we show that the poor performance of Bagheri andBonadonna (2016, https://doi.org/10.1016/j.powtec.2016.06.015) model discussed in Dioguardi et al. (2018,https://doi.org/10.1002/2017JB014926) was mainly due to the typos in the equations presented in theiroriginal manuscript. We believe that the iterative methodology for calculating the drag coefficient is notstrictly necessary for our data set. In this reply, however, we also include results of the intercomparison studyamong different drag models using the iterative methodology. Results show that the performance of thedifferent drag models considered in the intercomparison study is not significantly affected by the employedmethodology (direct vs. iterative) and that, regardless the employed methodology and unlike what has beenstated in the comment 2019JB017697, our model has the best performance in reproducing theexperimentally measured terminal velocities.
