Advantages of Continuum Modeling

Definition

The advantages of continuum modeling refer to the benefits gained by treating a multiphase system as a continuous medium rather than focusing on discrete particles or molecules. This approach simplifies the analysis of complex flow behaviors and allows for the use of established mathematical frameworks to predict system dynamics, making it a powerful tool in various engineering applications. By applying continuum modeling, researchers can efficiently handle large-scale systems while maintaining accuracy in simulations and predictions.
