Crossflow refers to the movement of fluid or air in a direction perpendicular to the primary flow direction, often used in engineering to enhance mixing or heat transfer. It is a fundamental principle in designing heat exchangers, cooling towers, and various aerodynamic applications to optimize efficiency and performance.
A shell and tube heat exchanger is a type of heat exchanger design that consists of a series of tubes, one set carrying the hot fluid and the other the cold, allowing heat transfer between the two fluids. It is widely used in industries due to its robust design, flexibility to handle high pressures and temperatures, and ease of maintenance and cleaning.
