Forced Convection in Heat Transfer
Forced convection is a type of heat transfer that occurs when a fluid, such as air or water, is forced to flow over a surface or through a tube, enhancing the rate of heat transfer. This is in contrast to natural convection, where heat transfer occurs due to the buoyancy of the fluid.
Examples of Forced Convection
Chilling effect of cold wind on warm body
- This is an example of natural convection, as the heat transfer is occurring due to the movement of the air caused by the temperature difference. However, it is not an example of forced convection, as there is no external force causing the air to flow.
Fluid passing through the tubes of a condenser and other heat exchange equipment
- This is an example of forced convection, as the fluid is being forced to flow through the tubes by a pump or other external force. This enhances the rate of heat transfer between the fluid and the surface of the tube.
Heat flow from a hot pavement to surrounding atmosphere
- This is an example of natural convection, as the heat transfer is occurring due to the buoyancy of the air caused by the temperature difference. There is no external force causing the air to flow, so it is not an example of forced convection.
Heat exchange on the outside of cold and warm pipes
- This is an example of forced convection, as the fluid is being forced to flow over the surface of the pipe by an external force, such as a pump or the pressure of the fluid itself. This enhances the rate of heat transfer between the fluid and the surface of the pipe.
Conclusion
In summary, forced convection is a type of heat transfer that occurs when a fluid is forced to flow over a surface or through a tube. The examples of forced convection include fluid passing through the tubes of a condenser and other heat exchange equipment, and heat exchange on the outside of cold and warm pipes.
