The effective use of Autodesk Simulation CFD for Turbomachinery applications requires fundamental knowledge of Computational Fluid Dynamics (CFD) and the software simulation use. Proficiency in these areas will ultimately help to improve both the design process and product performance. In this class, the fundamentals of the CFD process and its impact on Turbomachinery designs will be introduced to establish the initial foundation of simulation skills. A practical exercise of a simple centrifugal pump will then be used to put these skills into actual practice. The progression of a typical CFD simulation starts from the CAD model, the meshed model, to solving and convergence, and finally results visualization. During this workflow, best practices and pitfalls of CFD in Turbomachinery modeling will be discussed. Finally, the powerful post-processing tools of Autodesk CFD will be exposed to interpret Turbomachinery results and make decisions for modifying the design.

This talk will focus on transient coupled effects of conduction and radiative heat transfer in turbine rotor segments. Rotors at ambient are to be heated to extremely high temperatures, following certain metallurgical criteria. We'll use a computational fluid dynamics (CFD) simulation approach to analyze the rotor surface temperature, track the temperature trend vis-à-vis surface-to-core variation, and estimate transient heating time and surface heat flux. This simulation is needed to establish criteria required for testing rotors for meeting metallurgical properties under accelerated heating conditions. Challenges faced before obtaining a solution include reducing computational time, modeling complexity in geometrical features, setting up boundary conditions, and meshing. We'll also discuss basics of heat transfer and fluid mechanics, association of heater control logic, and the application of Autodesk CFD simulation tool to thermal engineering problems, as well as an analysis of results.
This class will explore the computer-aided thinking and design process that the Nairobi-based Engineering Team from a leading social enterprise uses to create new, income-generating products for the poorest segment of Africa’s population: small-scale farmers. Developing irrigation products that are affordable and uniquely tailored to the complex needs of small-scale farmers in Africa is a design challenge with the potential to improve the lives of millions. Examples from the work of KickStart International will illuminate how Inventor software, Simulations Mechanical software, and Autodesk CFD software are used to address this challenge more efficiently. KickStart has been expanding their line of human-powered irrigation pumps for more than 15 years, and the introduction of Autodesk, Inc., software and 3D printing have improved workflow by shortening the concept-to-completion product-development cycle and offset some of the challenges of prototyping and batch producing locally, in Kenya, on the way to mass manufacture. This session features Inventor Professional, CFD, Fusion 360, and Simulation Mechanical.
