Convection | Definition, Examples, Types, Facts | Britannica Convection, process by which heat is transferred by movement of a heated fluid such as air or water Natural convection results from the tendency of most fluids to expand when heated—i e , to become less dense and to rise as a result of the increased buoyancy
Convection - Definition, Examples, Types What Is Convection? Convection is the process of heat transfer within a fluid due to the movement of the fluid itself When a part of the fluid becomes warmer, it typically becomes less dense and rises, while cooler, denser fluid sinks This creates a flow that redistributes heat
What is Convection? - BYJUS Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids 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: What Is It How Does It Work? - Sciencing Convection is a type of heat transfer (similar to conduction or radiation) that operates on the physical movement of particles that creates a physical transfer and cycle of energy
CONVECTION | English meaning - Cambridge Dictionary Warm air rises by the process of convection This gradient, established and maintained by the surface buoyancy flux through the process of turbulent convection, is what draws fluid in from the external reservoir
Convection: Definition and Examples - Science Facts Convection is the heat transfer process from one region to another due to the movement of fluids like air or water The initial heat transfer occurs through conduction, but the primary transfer occurs through convection
What is Convection - Definition - Thermal Engineering When heat is to be transferred from one fluid to another through a barrier, convection is involved on both sides of the barrier In most cases the main resistance to heat flow is by convection
What does convection mean? - Definitions. net Convection is the concerted, collective movement of ensembles of molecules within fluids and rheids Convection of mass cannot take place in solids, since neither bulk current flows nor significant diffusion can take place in solids
Convection - definition of convection by The Free Dictionary convection 1 The upward motion of a body of air which transfers heat from ground level to the upper part of the atmosphere 2 Heat transfer by means of currents circulating through fluids
