Swizzle

The term "swizzle" can refer to several distinct concepts, primarily in the realms of cocktails, computer graphics, and chemical engineering.

In the context of cocktails, a swizzle is a type of mixed drink typically made with rum, crushed ice, and fruit juices, often served in a tall glass. The defining characteristic of a swizzle is its preparation method, which involves rapidly agitating the ingredients with a swizzle stick. This stick, traditionally a sprig of the swizzle stick plant (Quassia amara), is spun between the palms to churn and aerate the drink, creating a frothy texture. Popular examples include the Rickey Swizzle and the Mint Swizzle.

In computer graphics, swizzling is an operation that rearranges the components of a vector. For instance, a 3D vector (x, y, z) could be swizzled to (y, x, z) to swap its first two components, or to (z, z, z) to create a new vector where all components are the original z value. This operation is commonly used in shader programming and graphics hardware to efficiently manipulate vector data.

Within chemical engineering, a swizzler or swizzle pipe is a type of heat exchanger. It is characterized by a shell and tube design where the tubes are equipped with internal helical fins or baffles that cause the fluid to follow a swirling or "swizzled" path as it flows. This increased turbulence enhances heat transfer efficiency between the shell-side and tube-side fluids. The design is particularly effective for viscous fluids or when precise temperature control is required.
