• 🅰️ Surface properties and fluid characteristics determine the type of condensation.

Questions & Answers

Q: What is condensation and how does it differ from boiling?

Condensation is the change of vapor to liquid at saturation temperature, unlike boiling where vaporization occurs at saturation temperature while adding heat.

Q: How does surface temperature affect condensation?

When the surface temperature is below the saturation level, condensation occurs as vapor loses heat to reach liquid state.

Q: What are the key heat transfer mechanisms involved in condensation?

Heat transfer in condensation involves convection, latent heat release during phase change, and subcooling of the liquid droplet formed.

Q: What types of condensation can occur on a surface?

Condensation can be film-wise or drop-wise, depending on the surface properties and fluid characteristics altering condensation behavior.

Summary & Key Takeaways

• Condensation is the change of vapor to liquid when reaching saturation temperature.

• Surface temperature below saturation level causes condensation.

• Heat transfer occurs through convection, latent heat, and subcooling in condensation process.
