Searching of the optimum tilt of the pipe at condensation by using gradient heatmetry

The aim of the study is to determine optimum tilt of the pipe at film condensation by using of gradient heatmetry. Dependence of heat flux per unit area on time and azimuthal angle are presented for vertical, horizontal and inclined pipe. Maximal heat transfer coefficients for experimental conditions are observed for the angle 20° from vertical. The gradient heatmetry gives high informational content, which opens up new possibilities for studies of heat transfer during condensation.
