Investigation of the Unsteady Flow Generated by an Axial Fan: Experimental Testing and Simulations

Blog Article

The unsteady flow measurement of a large axial fan with UNSCENTED diameter 1.829m (6 ft) has been carried out.The complex flow field generated by the fan is investigated through experimental testing and CFD/FEA simulation.The results presented in this paper can be divided into three parts.The first part consists of the experimental description of the test facility, velocity measurement, flow-field visualization, and stress/strain analysis of the fan blades.

The second part consists of the CFD simulation of the flow field.Simulation is carried out to analyze the flow pattern with and without a radiator attached to the fan casing.The results presented in this paper can be used Fruit Snacks as a reference for axial fan performance improvement in the future.
