Corrigendum to “A Quasi-Implicit and Coupled Multiscale Scheme for Simulating Combustion of Pellets of Core-Shell Structured Intermetallic Particles” [Combust. Flame 250 (2023) 112650] (Combustion and Flame (2023) 250, (S0010218023000354), (10.1016/j.combustflame.2023.112650))

The original simulations were conducted using an inaccurate expression for the effective density of core-shell particles. All the simulations were therefore repeated after updating the source code² with the following revised core-shell particle density model:[Formula presented] where, [Formula presented], denotes the effective particle density, [Formula presented] is the volume fraction of species [Formula presented] in the core-shell particle, and [Formula presented] is the density of species [Formula presented]. The previous model underestimated particle densities by at most 30%. Consequently, combustion velocities were over predicted by at most ∼20%. However, the trends of combustion velocities and temperature profiles, discussions, and conclusions were not affected. The revised set of Figures 8–12 and Table 6 are presented in this document. There is no significant change in the qualitative trends. The only perceptible differences in the figures are in the labels and legends. There is one minor change in the stability limit of the explicit scheme, as shown in Figure 10(a). In light of this, the following sentence on page 10 of the original paper “The explicit scheme becomes unstable for time steps greater than 3 µs, whereas the implicit and Crank-Nicholson schemes are observed to be stable for time steps as high as 1 ms.” is now modified and should read as: “The explicit scheme becomes unstable for time steps greater than 5 µs, whereas the implicit and Crank-Nicholson schemes are observed to be stable for time steps as high as 1 ms.” The authors deeply regret the error and humbly apologize for any inconvenience.
