A fundamental study on the flow past a circular cylinder ...

Flow patterns generated around a circular cylinder immersed in a uniform flow are shown in Figure 1 (Hughes & Brighton, 1999). In relation to the flow around an object, a combination of a uniform flow with a circular cylinder will be the simplest case. The pattern of this flow varies depending upon the Reynolds number.

Metal forming processes

Bulk forming processes Forging • It is a deformation process in which the work piece is compressed between two dies, using either impact load or hydraulic load (or gradual load) to deform it. • It is used to make a variety of high-strength components for automotive, aerospace, and other applications.

Slag Remelting (ESR) processes. Tool steels produced by VMR are observed to have superior toughness compared to ESR (5). Apart from mechanically induced stresses due to forging pressure, the hot forging dies are subjected tothermal stresses especially near surface of the diesthe , where they are in contact with the work piece.
