👉 A cross-flow, or cross-fluid, is a type of fluid flow where the direction of the fluid movement is perpendicular to the axis of the flow channel or pipe. In this configuration, the fluid moves in a series of alternating layers or streams, with each layer flowing in a direction opposite to the previous one. This results in a mixing effect between the layers, enhancing the interaction and transfer of properties such as heat, mass, or momentum. Cross-flow is commonly observed in microchannel reactors and heat exchangers, where it facilitates efficient and uniform mixing without the need for mechanical stirring, making it particularly useful in applications requiring precise control over fluid dynamics and thermal management.
