The effective thermal conductivity k e was measured for a continuous bubble column operating within the bubbly flow regime. k e was found to be independent of liquid flow rate but strongly dependent on gas flow rate and physical properties of the liquid phase over the ranges 0.1> u G >4 cm/s, 0> u L >3.4 cm/s, 0.00096> μ >0.0028 kg/m μ s and 0.047 >σ>0.072 N/m.
