Heat Transfer Coefficient

Heat transfer coefficient quantifies convective heat transfer between surface and fluid. Essential for HVAC design and heat exchanger optimization.

Convection Basics

Heat transfer coefficient (h) in W/(m²·K) or BTU/(hr·ft²·°F). Depends on fluid properties, flow conditions, and surface geometry.

Natural vs. Forced

Natural convection: 2-25 W/(m²·K), Forced convection: 25-250 W/(m²·K), Boiling: 2500-100000 W/(m²·K). Huge range by mechanism.

Design Applications

Higher coefficients mean better heat transfer. Fans and pumps increase coefficients by forcing fluid flow across surfaces.

Common Applications

HVAC system design, heat exchanger optimization, electronics cooling, building energy modeling, and industrial process design.

Conversion Tips

Forced convection much more effective than natural. Turbulent flow increases heat transfer but requires more pumping power.
