Friction stir channeling

The Friction stir channelling (FSC) process is based on the concept of transforming the void or tunnel defect originating in advancing side of Friction Stir process into continuous integral channel. The process was first invented and patented as manufacturing technique for heat exchanging devices and can have wide range application in compact heat exchanger industries. The important aspect for use of the channel in any thermal application is thermo-hydraulic performance. The geometrical parameters of channel (Shape, Cross Sectional Area, Surface Area, hydraulic diameter, Surface Roughness, and Length) decide the thermo-hydraulic performance of channel. Our research work is on the fabrication of continuous internal channels, geometrical characterization of the fabricated channels, study of effect of FSC process parameters on geometry of channels and hydrothermal performance measurement of the fabricated channels.
