In the work presented is a new approach to modelling the heat transfer in bubbly flow in the boundary layer. An approximate velocity distribution profile [1] is used in solution of energy equation. Presented have been two solutions to the problem, namely for a constant void fraction distribution, where an analytical temperature distribution has been obtained, and for a variable void fraction formulation, a more accurate solution, which is based on solution of three differential equations, namely: equation describing the lateral motion of bubbles, migration of gaseous phase and temperature distribution. It seems that the error incurred, in the case of small void fractions, between a constant and variable formulation is so small, that a simple analytical solution can be recommended for engineering purposes.
