Convection is a heat transfer process. When currents are produced, matter is moved from one location to another. So this is also a mass transfer process. Convection that occurs naturally is called natural convection or free convection. All matter contains heat energy. Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat.Convection. Convective heat transfer occurs as a result of the transfer of energy between a moving gas or liquid phase and a solid phase. Typical examples include the energy transfer which occurs in process heat exchangers or in air cooled exchangers. Here, the mechanisms can be divided into natural convection and forced convection processes.Convection is one form of energy transfer where heat energy is transferred by large scale movement in a gas or liquid. Convection currents form, which are streams of gas or liquid powered by convection. Some of this movement is caused by differences in density.

In a convection oven, dry moving air generated by a fan and a heating element is used and the result is faster cooking time (25% ...What is the difference between conduction and convection? The initial heat transfer between the object and the fluid takes place through conduction, but the bulk heat transfer happens due to the motion of the fluid. Convection is the process of heat transfer in fluids by the actual motion of matter. It happens in liquids and gases. Just like a hot-air balloon lifting off the ground, blobs or "parcels" of hot air rise from the ground, carrying hot air skyward. This transfer of heat energy away from the ground by the vertical movement of air is called "free convection" or "natural convection." A hot air balloon rises because warmer air is less dense than cool air.What is the difference between conduction and convection?

Convection, especially Rayleigh鈥揃茅nard convection, where the convecting fluid is contained by two rigid horizontal plates, is a convenient example of a pattern-forming system. When heat is fed into the system from one direction (usually below), at small values it merely diffuses ( conducts ) from below upward, without causing fluid flow. Convection - When warm, moist air near the surface rises to be above the heavier cool, dry air this is a form of heat transfer or convection. The rising motion typically cools the air. As the air cools, it reaches the dewpoint and all of the moisture in the air condenses- forming clouds. Depending on many factors, these clouds can form rain ...A good example would be heating a tin can of water using a Bunsen burner. Initially the flame produces radiation which heats the tin can. The tin can then transfers heat to the water through conduction. The hot water then rises to the top, in the convection process.
