Low-order Model of Supersonic Fluidic Oscillator for Superplastic Forming

The Superplastic Forming process involves gas injection from a variable pressure supply, to form a heated metallic sheet into a complex automotive body panel shape onto the surface of a die. The current process involves excessive forming times which allow residual stresses to relax and avoid cracking and tearing. Research shows that pressure pulsations of the gas supply increases allowable material strain rate, reducing required manufacturing time. Our research shows that a Supersonic Fluidic Oscillator, due to the absence of moving parts, is capable of reliably generating the required pressure fluctuations under the extremely high temperatures present. Design of these devices requires use of computationally expensive fluid dynamics solutions of the complex compressible flow which are prohibitive for use in industry. The objective is to develop a simplified mathematical model with suitable accuracy to allow the partner to quickly design these devices and become a world leader in this area.
