The two widely used experimental methods for pool
boiling experiments are evaluated. Boiling heat transfer
data employing either the water heating or the electric
heating method obtained by various researchers are
compared and discussed. The electric heating method is a
constant heat flux process, while the water heating
method represents a pseudo-exponential temperature
profile for the heating water along the tube. It is
concluded that the temperature profile along the tube is
the major cause of the difference between results from
the two methods. The parameters that shape the
temperature profile and cause differences are discussed.
