Products to determine optimal packaging typically consider permutations of packing options and select one that likely minimizes total costs while preventing the likelihood of product damage. However, such products use algorithms where the runtime increases exponentially with the addition of a box or an item in the input, thus making them impractical for orders that require multiple boxes and items. Moreover, such products typically do not take merchant and product variations and specialized needs into consideration. This disclosure describes an efficient general-purpose algorithm to generate packing recommendations. The algorithm produces near-optimal packing recommendations within a reasonable time.

Moving particles were used to describe the liquid phase and the vapor phase was evaluated using real vapor sate equation. The bubble-liquid interface was set to be a free surface boundary which could be captured according to the motion and location of interfacial particles. The behaviors of coalescence between two identical bubbles predicted by the MPS method were in good agreement with the experimental results reported in the literature. Numerical results indicated that the rising velocity of the trailing bubble was larger than that of the leading bubble. Both of the leading bubble and the trailing bubble rose faster than the isolated bubble. After coalescence, the coalesced bubble showed velocity and volume oscillations. The time of the volume oscillations increased with increasing initial bubble diameter. The wake flow and vortex would form behind the coalesced bubble.
