  • Profile Summary

    The Multiphase Computational Fluid Dynamics group at University of Wisconsin-Madison is led by Professor Mario F. Trujillo and is associated with the Engine Research CenterMechanical Engineering and Engineering Physics Departments. We are interested in a variety of multiphase flow problems ranging from micron-size particles transported in analytical flow fields to various industrial liquid spray applications. A driving motivation in our work is our desire to understand how multiphase physical phenomena manifest itself and in determining the dominant mechanisms that govern it. In this spirit, we employ numerical techniques to simulate physical processes at a high level of detail, which allows for this type of analysis. Our simulations are generally only the first part of our study, which subsequently evolves into an analytical investigation of the underlying physics. Since computations form an integral part in our research, we also devote significant time to the development and use of numerical methods for treating gas-liquid interface dynamics. A principle long-term objective in our group is to gain insights into these multiphase processes, which can guide the design and operation of their associated engineering components.
