- •
A modified direct method has been proposed for accurate void fraction calculation.
- •
PMM inherits the simplicity and computational advantage of the direct method.
- •
There is a minimum particle grid number required to reach the stable simulation.
- •
PMM shows even higher computational efficiency than that of analytical approach.
- •
PMM exhibits potential to handle arbitrarily complex domain and particle geometries.
