Natural Convection occurs when a warmer less dense fluid is pushed away by a cooler denser fluid. Forced Convection occurs when an outside force pushes a fluid, such as water of air, to make it move and transfer heat. A fan is a perfect example. Im pretty sure air, and heat vents are examples too. An air conditioner is definitely an example.

SteveForced convection occurs when a fluid flow is induced by an external source like a pump or fan, while natural convection happens due to density differences within the fluid causing fluid motion. Forced convection is generally more predictable and controllable, while natural convection relies on buoyancy forces and can vary based on the surrounding environment.

What are the different types of convection?
The three main types of convection are natural convection, forced convection, and mixed convection. Natural convection occurs due to density differences caused by temperature variations. Forced convection involves the use of external means like fans or pumps to enhance fluid movement. Mixed convection combines both natural and forced convection mechanisms.
Convection always occurs in what two forms?
Convection typically occurs in two forms: natural convection, driven by buoyancy forces due to temperature differences, and forced convection, driven by external factors like fans or pumps. Natural convection occurs in fluids (liquids and gases) due to density variations caused by temperature gradients, while forced convection involves the use of mechanical devices to circulate the fluid.
What kind of heat transfer does wind represent?
Wind represents both forced convection and natural convection heat transfer. Forced convection is when the movement of a fluid is driven by an external force (such as wind blowing over a surface), while natural convection is when heat is transferred through a fluid due to density differences caused by temperature variations.
What is difference between free and forced convection?
free convection : the transfer of heat resulting from differences in density of air, that thereby causes the flow of air. mechanical convection the transfer of heat resulting from a blower or fan that actively forces heated air throughout all areas
What does free and forced convection mean?
Free convection refers to the natural flow of fluid (liquid or gas) caused by density differences due to temperature variations. Forced convection, on the other hand, refers to the fluid flow driven by an external force, such as a pump or a fan.
