A convection oven (also known as a fan-assisted oven, turbo broiler or simply a fan oven or turbo) is an oven that has fans to circulate air around food [1] to create an evenly heated environment. In an oven without a fan, natural convection circulates hot air unevenly, so that it will be cooler at the bottom and hotter at the top than in the ...
Both of these types of convection, either natural or forced, can be internal or external because they are independent of each other. [ citation needed ] The bulk temperature , or the average fluid temperature, is a convenient reference point for evaluating properties related to convective heat transfer, particularly in applications related to ...
Ovens usually can use a variety of methods to cook. The most common may be to heat the oven from below. This is commonly used for baking and roasting. The oven may also be able to heat from the top to provide broiling (US) or grilling (UK/Commonwealth). A fan-assisted oven that uses a small fan to circulate the air in the cooking chamber, can ...
Unlike conventional ovens, which cook food by surrounding it with hot air, convection ovens circulate the air. Convection ovens are built with a fan placed in the back of the oven.
Forced convection is a mechanism, or type of transport, in which fluid motion is generated by an external source (like a pump, fan, suction device, etc.). Alongside natural convection , thermal radiation , and thermal conduction it is one of the methods of heat transfer and allows significant amounts of heat energy to be transported very ...
A fan heater, also called a forced convection heater, is a kind of convection heater that includes an electric fan to speed up the airflow. They operate with considerable noise caused by the fan. They have a moderate risk of ignition hazard if they make unintended contact with furnishings.

By comparison, most modern "warm air" furnaces typically use a fan to circulate air to the rooms of house and pull cooler air back to the furnace for reheating; this is called forced-air heat. Because the fan easily overcomes the resistance of the ductwork, the arrangement of ducts can be far more flexible than the octopus of old. In American ...
