n. convection Air heated by a space heater rises and is replaced by cool air, creating a convection current that circulates hot air throughout a room. All rights reserved.the transfer of heat by the circulation or movement of the heated parts of a liquid or gas.the vertical transport of atmospheric properties, especially upward (distinguished from a process of heat transfer through a gas or liquid by bulk motion of hotter material into a cooler regionthe process by which masses of relatively warm air are raised into the atmosphere, often cooling and forming clouds, with compensatory downward movements of cooler airthe slow circulation of subcrustal material, thought to be the mechanism by which tectonic plates are movedHeat transfer in a gas or liquid by the circulation of currents from one region to another.Fluid motion caused by an external force such as gravity.Current in a fluid caused by uneven distribution of heat.

For example, air on a part of the Earth's surface warmed by strong sunlight will be heated by contact with the ground and will expand and flow upward, creating a region of low pressure below it; cooler surrounding air will then flow in to this low pressure region. the passing of heat through liquids or gases by means of currents.

By reviewing literature, it reveals that it has not been studied enough especially in mixed When it begins to melt and the liquid PCM starts to move, the transfer of heat is due to DuraCrete [21] proposed an experience method which considers that within 0 ~ [increment of x] ([increment of x] is the total This motion is called thermocapillary flow or Marangoni The results for velocity and temperature distribution reveal the flow kinematics under the effects of key physical parameters of the problem namely non linear shrinking parameter s, magnetic parameter M, porosity parameter K, mixed Based on the Random House Unabridged Dictionary, © Random House, Inc. 2020Collins English Dictionary - Complete & Unabridged 2012 Digital Edition Convection is the movement of heat because of the movement of warm matter.. For example, atmospheric circulation moves warm air to cool places, causing wind.Wind, in turn, can enter and cool a room if the window is open.

Convection definition: Convection is the process by which heat travels through air, water, and other gases and... | Meaning, pronunciation, translations and examples The movement of the clouds, the ocean currents and many types of heaters are examples of convection.

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. © William Collins Sons & Co. Ltd. 1979, 1986 © HarperCollins The air thus circulates by convection, creating winds.

Published by Houghton Mifflin Company.The American Heritage® Science Dictionary Eventually, as the cooler molecules are heated, they move as well, and a convection current forms, transferring the heat. Convection is where the hot, less dense part of a fluid rises, and the cooler, denser part sinks. Copyright © 2002, 2001, 1995 by Houghton Mifflin Company. Convection, process by which heat is transferred by movement of a heated fluid such as air or water. Published by Houghton Mifflin Harcourt Publishing Company. convection synonyms, convection pronunciation, convection translation, English dictionary definition of convection. Convection definition is - the action or process of conveying. Convection happens when there is a difference in temperature between two parts of a liquid or gas.
