This paper describes the application of computational fluid dynamics (CFD) to fan design as part of the PAX Scientific product development cycle. Six-inch fans are investigated using a simulation configuration designed to match in-house testing facilities. Grid generation and flow simulations are carried out using a commercial CFD software (Fluent). The segregated solver is used to run steady state RANS simulations with a Realizable k-ε turbulence scheme. Performance predictions (flow and pressure generated, power required) are in agreement with experimental testing values, with a margin of error ranging from less than 1% to less than 10%.
