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.

Value Stream Mapping for Lean Manufacturing …

manufacturing is to reduce waste in an operation, such as long lead times, defects and material waste. In order to visually display where waste occurs in the process, a value stream map (VSM) is drawn. VSMs are often used to assess current manufacturing processes as well as create ideal, future state processes.
