Which type of convection relies on mechanical means to move a fluid to increase heat transfer?

The concept of forced convection is rooted in the use of mechanical means, such as fans or pumps, to enhance the movement of a fluid, which significantly improves heat transfer. Unlike natural convection, where fluid movement occurs due to buoyancy differences resulting from temperature variations, forced convection actively pushes the fluid to circulate. This increased flow rate leads to a higher rate of heat transfer, making it particularly effective in applications like heating and cooling systems where efficient temperature control is essential.

In scenarios where forced convection is applied, the fluid is consistently moved over surfaces and into contact with heat sources, allowing for more uniform thermal distribution and faster heat exchange. This principle is widely utilized in various engineering applications, making it a critical concept in thermal management and heat exchangers.
