Determination of heat transfer intensity in laminar liquid film flow
Analytical study of the stabilized heat transfer for the laminar liquid film flow was carried out. The method for the calculation of local heat transfer in laminar film flowing down a vertical surface was proposed. The wetted surface curvature and external heat exchange influence on heat transfer in laminar film was established analytically. Experimental investigation of heat transfer in thermal en-trance region for laminar film was performed as well. The surface cross curvature influence on the local transfer in the thermal entrance region of high viscosity liquid film flow was established experimentally.
