Heat Transfer Coefficient
Chemical Engineering · Mechanical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: The heat transfer coefficient quantifies the rate of heat transfer per unit area per unit temperature difference. It is used in sizing heat exchangers and predicting thermal performance.
Example in context
“The heat transfer coefficient for the flow inside the tube was determined using the Dittus-Boelter correlation.”
“Tüp içindeki akış için ısı transfer katsayısı Dittus-Boelter korelasyonu kullanılarak belirlendi.”
Where engineers use it
Engineers use local heat transfer coefficients in designing finned tubes and evaluating convective heat transfer in process equipment.
Synonyms: film coefficient, convective coefficient
In Mechanical Engineering
The heat transfer coefficient quantifies the rate of heat transfer per unit area per unit temperature difference between a solid surface and a fluid. It is a critical parameter in designing heat exchangers and thermal systems.
“The engineer calculated the heat transfer coefficient for the shell-and-tube heat exchanger to ensure adequate cooling capacity.”
