Heat Convection

Heat convection is the transfer of heat particles through liquid or gas.

The Equation Interpreted in Cartesian

`Q = h · A · (T_surface − T_fluid)``

• Q = heat transfer rate (watts) – this is the flow of heat particles
• h = convective heat transfer coefficient (depends on fluid, flow type, geometry) – this is the aetherspace of matter
• A = surface area in contact with the fluid
• T_surface = temperature of the solid surface
• T_fluid = temperature of the fluid away from the surface – this is the density of heat particles to be emitted

Liquids and gases have more space particles than solid particles.

Since heat particles always go with space particles, this leads to the transfer of heat.
