Pinch - Mathematics and Science

Mathematics and Science

• Pinch analysis is a methodology for minimising energy consumption of chemical processes by calculating minimum energy consumption and by optimising heat recovery systems etc. It is also known as process integration, heat integration, energy integration or pinch technology.
• Pinch (plasma physics), the compression of a plasma filament by magnetic forces, or a device which uses this effect for magnetic fusion energy (the Z-pinch is a special case of such a device)
• The point of maximum constraint or minimum flow in various chemical engineering processes
• Pinch point (economics), the level of inventory below which consumers become concerned about security of supply
• Pinch point (mathematics), a type of singular point on an algebraic surface
• Pinch temperature, the key point in a process when using pinch analysis techniques to minimise energy use.
• Pinching (technology), is a multitouch gesture to control touchscreens
