Convection
Chemical Engineering · Engineering Fundamentals · Last updated: July 30, 2026 · How this entry was written
Definition: Heat transfer through the macroscopic movement of a fluid, driven by density differences (natural convection) or external forces (forced convection). It is a dominant mode of heat transport in many process units.
Example in context
“Forced convection from a hot fluid to a cooler pipe wall is essential for designing shell-and-tube heat exchangers.”
“Sıcak bir akışkandan daha soğuk bir boru duvarına zorlanmış konveksiyon, gövde-boru tipi ısı değiştiricilerin tasarımında esastır.”
Where engineers use it
Convection calculations are used by engineers to determine heat transfer coefficients in reactors, condensers, and evaporators. Understanding natural vs forced convection is key for process design and equipment sizing.
Synonyms: convective heat transfer
Antonyms: conduction
In Engineering Fundamentals
The transfer of heat by the movement of a fluid such as air or water, in which warmer regions rise or are circulated while cooler regions take their place.
“Natural convection carries warm air upward, so the heaters were placed near the floor.”
Practice: can you use “Convection” at work?
A trainee must choose between natural and forced convection to cool a product stream and justify the selection based on flow conditions.
Show a model answer
“Convection is a primary mode of heat transfer in fluid-based processes.”
