MODULE 3

Section 1:   

Boundary Layer and Turbulence

Section 2:   

Pressure Drop and Friction Factor

Section 3:   

Heat Transfer Coefficient

The first part of this module presented the mechanism of convection with the fluid remaining in its original state (liquid or vapor) despite the heating or cooling that it experiences. 

Now the mechanism of convection with phase change of the fluid due to the high heat fluxes involved will be presented. This situation occurs when:

• the solid body temperature is sufficiently higher than the saturation temperature of the liquid, or
• the solid body temperature is sufficiently lower than the condensation temperature of the vapor.
