Friction stir channeling

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.

Channel formation during friction stir channeling process—A material flow study using X-Ray micro-computed tomography and optical microscopy

In this study, an experiment is performed to investigate material flow and its implication on the channel formation in friction stir channeling process. X-ray Computed Tomography in combination with optical microscopy is used to analyse bulk material …
