Light-weight and high strength alloys such as Al-Mg alloys are used in order to reduce the weight of industrial components. However these materials should be formed at elevated temperatures due to their poor formability at room temperature. Hot metal gas forming is one of the high-tech forming processes that is used to solve this problem. Recent investigation on tube hydroforming showed positiv...

The application of heated thin film gauges to the measurement of mean skin friction in compressible flow is described. It is shown that the calibration of the gauges is independent of Mach number, at least up to M = 3, provided the fluid properties are calculated at the appropriate film temperature. The gauges are calibrated by reference ~ surface tubes and also by comparison with the theoretic...
