    Corrigendum to “How can the appropriate near-wall grid size for gas cyclone CFD simulation be estimated?” [Powder Technology 396 (2022) 327–344, (S0032591021009128), (10.1016/j.powtec.2021.10.031)]

    The author regrets errors that occurred in the original article [1], which are now amended as follows: The near-wall grid size [mm] for cyclone A1 cone of “0.8764” in Table 3 of the original article [1] is corrected to be “0.6550”. The near-wall grid size [mm] for cyclone A1 vortex finder of “0.6550” in Table 3 of the original article [1] is corrected to be “0.8764”. Although the author has already described in section 3.4. Grid independent solutions and grid convergence index of the original article [1] that the experimental data of Hoekstra [2] displayed by circle symbols in Fig. 6 of the original article [1] was employed to compare with the simulated results performed in the original article [1] as “Further, the numerical uncertainties were approximated by GCI as illustrated by error bars on the normalized velocity profiles, which were compared with experimental data of Hoekstra [9], as represented in Fig. 6.” (Number “9” displayed in the brackets refers to the reference order for the Hoekstra's work [2] in the original article [1].), this information should also be added to the Fig. 6 caption of the original article [1] to prevent the confusion of readers. Therefore, the Fig. 6 caption of the original article [1] is now changed to the more appropriate Fig. 6 caption as “Radial profiles of mean tangential and mean axial velocities for cyclone B2 at z/D<inf>b</inf> = 0.75 predicted by (a) three different grid resolutions and (b) fine grid level with discretization error bars (EXP [9])”. Note that number “9” displayed in the brackets refers to the reference order for the Hoekstra's work [2] in the original article [1]. Furthermore, the same set of Hoekstra's experimental data [2] was also used in the graphical abstract of the original article [1] published on online pages as displayed by circle symbols. The name “ter Linder” in section 4.2. Mean static pressure and pressure drop of the original article [1] is corrected as “ter Linden”. An explanation of the Greek symbol “ν” in the inline equation of Stokes number represented in section 4.4. Collection efficiency of the original article [1] was not given in any section of the original article [1]. Hence, this Greek symbol is now described in this erratum as “ν is the kinematic viscosity of fluid [m<sup>2</sup> s<sup>−1</sup>]”. The author would like to apologise for any inconvenience caused.
