Fan Characterization and Performance Analysis with CFD
Fans are essential devices that are critical to many functions of modern life. We show how CFD can optimize fans of all shapes and sizes and not be a cartoon (validate to test).
Fans are essential devices that we encounter every day without much thought, but they are critical to modern life. From small devices in your computer laptop to large air movers for building ventilation, you will encounter these items throughout the day. These analyses can be inherently challenging problems that involve transient fluid structure interaction. We are interested in developing a fan characterization curve or determining sources of acoustic noise. At Predictive Engineering, we have years of experience and expertise in the models and methods for CFD fluid and FEA structural analysis of fan and turbine blades.
Build and test has been a traditional method for fan development over the years, and technologies such as 3D printing and rapid prototyping have significantly reduced cost and time. However, there are still limits to the number of design iterations you can evaluate and the amount of information you can obtain. With CFD simulations, we can take advantage of model parameterization and optimization to automate running hundreds of studies and delve deeper into model results. With building and testing, you typically only measure flow and pressure to characterize the fan. With simulation, we can understand everything that is happening in the flow field, from pressure and structural loading on the blades to sources of acoustic noise. These results can be used to inform design decisions and achieve better performing designs.
