1. Heat Transfer Examples

2. Example (2) A two-tube-pass, one shell-pass, shell-and-tube heat exchanger: condenser, evaporator, feedwater heater, steam generator The first tube-pass flows is in the same as the shell-pass: parallel flow. The second one flows in the opposite direction to the shell- pass: counterflow.

3. Example (3) Blast furnace: air is blowing into the furnace to maintain temp. that is higher than 800°C. Melting iron flows into ladle. Continuous casting can be achieved by cooling the molten iron in a convey system. Precise temperature control is critical to the quality of the final product.

4. Example (4) Weather Convection Day time: sea breeze coming toward the land as a result of natural convection Night time: wind blowing from land to sea because of the natural convection
