What is Condenser?

Condenser is a special type of Heat Exchanger in which hot vapors transfer their latent heat to the colder fluid and thus results into condensation of vapors into liquid phase.

What is the Significance of Reynolds Number in Heat Transfer of Condensing Vapors?

The heat transfer coefficient (h) is a measure of how effectively heat is transferred from a hotter surface to a cooler fluid. In the context of condensing vapor, the Reynolds number is relevant because it helps determine the flow regime over the surface where condensation is taking place. If the vapor condenses into droplets or a thin liquid film, it can alter the Reynolds number and transition the flow from laminar to turbulent, even at relatively lower velocities.

The Vapor when condensed into its liquid form, forms a thin film around the internal perimeter of the tubes. If this liquid film have a higher turbulence, then a better heat transfer can be achieved in a condenser.
