Visualization

Definition

Visualization is the process of creating graphical representations of data and information to aid in understanding and interpreting complex systems. In the context of multiphase flows, especially gas-liquid flow regimes, visualization helps in identifying flow patterns, interactions between phases, and overall system behavior through images, graphs, and simulations.
