Convection Heat Transfer Calculator

Convection heat transfer is a mode of heat transfer where energy is transferred between a surface and a fluid (liquid or gas) due to the bulk motion of the fluid. This process involves the movement of fluid particles carrying thermal energy from a hot surface to a cooler surface or vice versa.

2. where:

• $Q$ is the heat transfer rate (W or J/s),
• $h$ is the convective heat transfer coefficient (W/(m²·K)),
• $A$ is the surface area for heat transfer (m²),
• Ts​ is the surface temperature (K),
• T∞​ is the fluid (or ambient) temperature (K).
