What is Dropwise & Filmwise Condensation?

Condensation occurs when a vapor transitions to a liquid phase on a cooler surface. There are two main types:

1. Dropwise Condensation: Small droplets form on the surface. This type offers high heat transfer efficiency as droplets continuously remove heat from the surface.

2. Filmwise Condensation: A continuous liquid film forms, resulting in lower heat transfer rates due to thermal resistance of the film.

Studying these phenomena helps understand surface properties, heat exchanger efficiency, and industrial condensation processes.

Working Principle of Dropwise & Filmwise Condensation Apparatus

The apparatus operates on condensation heat transfer principles:

1. Vapor Generation: Hot vapor is introduced to the condensing surface.

2. Condensation Observation: Dropwise condensation occurs on hydrophobic surfaces, while filmwise condensation occurs on hydrophilic surfaces.

3. Temperature Measurement: Sensors record surface and vapor temperatures.

4. Data Analysis: Heat transfer coefficients, condensation rates, and thermal performance are calculated.

This allows users to observe and compare condensation mechanisms under controlled conditions.
