Heat Convection

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Heat convection (one of three ways to heat transfer: conduction, convection and radiation) is the flow of heat through currents within a fluid (liquid or gas).      


\(Q =   h  A  \Delta T    \)

\(Q =   h  A  \left(  T_h \;-\; T_c  \right)     \)


\(Q\) = heat conversion or transfer

\(h\) = heat transfer coefficent

\(A\) = cross sectional area  

\(\Delta T\) = temperature differential

\(T_h\) = higher temperature

\(T_c\) = cooler temperature
