Explain why heat transfer may be enhanced using a staggered

Explain why heat transfer may be enhanced using a staggered bank of tubes in cross flow relative to aligned tubes?

Solution

Staggered bank of tubes are commonly-employed design elements in heat exchangers. Both plain and finned tube banks are widely found. Tube bundles are a sub-component in shell-and-tube heat exchangers, where the flow resembles crossflow at some places, and longitudinal flow elsewhere. The flow may be single-phase or multiphase: boilers and condensers containing tube banks find a wide range of applications in industry, in addition there may becombustion, e.g., in a furnace heat exchanger.
