baffles

Baffles are commonly used in heat exchangers to improve the heat transfer efficiency by enhancing the fluid mixing and increasing the heat transfer area.

Baffles are essentially thin plates or strips that are inserted inside the heat exchanger, perpendicular to the direction of fluid flow. They can be either solid or perforated, and can be placed in a variety of configurations, depending on the specific application.

By introducing baffles into the heat exchanger, the fluid flow is disrupted and redirected, causing turbulence and improving the heat transfer efficiency. This is because the turbulence helps to break up any boundary layers of fluid that may be present, which can reduce the heat transfer rate. The baffles also increase the surface area available for heat transfer by creating more contact between the fluid and the heat exchange surface.

The use of baffles is particularly important in applications where there are large temperature differences between the two fluids, or where there are high flow rates. Without baffles, the heat transfer rate would be significantly reduced, leading to lower overall efficiency and potentially longer processing
