Compressible flows are ubiquitous in engineering applications and encompass a wide range of fluid regimes, from low speed subsonic to supersonic and hypersonic flows. The behavior of the flow field changes dramatically at velocities near and above the speed of sound, making these flows challenging to simulate. This presentation will discuss strategies for solving compressible flow problems using ANSYS CFD software. Best practices for subsonic, transonic, supersonic, and hypersonic viscous flows will be covered, focusing on meshing, turbulence models, solver type (density-based versus pressure-based), boundary conditions, discretizations, and solver controls. The discussions will be highlighted by CFD examples covering a range of applications and flow regimes.
Frank received his BSME from Clemson University in 1983, and an MSME from Purdue University in 1986. He subsequently worked for over three years as a mechanical engineer at General Electric Aircraft Engines in Cincinnati, OH. At General Electric, Frank worked in several turbomachinery analysis groups supporting a wide range of disciplines, including heat transfer and secondary flows, aeroacoustics, and hypersonic vehicle propulsion. Frank also completed the Edison Engineering Program at General Electric, which provided him comprehensive training all areas of in aircraft engine design and analysis.
Frank returned to graduate school in 1989 to pursue a Ph.D. in Mechanical Engineering at Iowa State University. With curriculum consisting of a strong focus on thermo-fluids and computational fluid dynamics, his dissertation topic dealt with the development numerical methods for calculating viscous free surface flows with application to satellite propulsion dynamics. This work was later published in the Journal of Computational Physics. Upon graduating in 1993, he worked as a project engineer at the Allison Engine Company in Indianapolis, IN, developing numerical methods for analyzing unsteady rotor-stator interaction high pressure turbines. Frank later joined Fluent Inc. in 1995 as a technical support engineer, where he provided support and training services to CFD software clients in the aerospace, automotive, HVAC, and turbomachinery industries.
In 2006, Fluent Inc. became part of the ANSYS Inc. family, and Frank migrated to his current role as a lead support engineer within the ACE group. Within ANSYS, he maintains a company-wide recognition as a fluids and CFD application specialist for rotating machinery, aerospace, heat transfer, and multiphase applications, providing company wide support, training, consulting, and testing for a wide range of fluids projects and activities.
