*** General Introduction ***
This dataset contains the data supporting the publication "Wet particle collisions simulated using the Local Front Reconstruction Method, a DNS approach" published in Chemical Engineering Science. In this work, the collision of a wet and dry particle is simulated using Direct Numerical Simulations. In this framework, the Local Front Reconstruction Method, a Front Tracking approach, is used in combination with the Immersed Boundary Method. For further reference this publication should be consulted.
