The investigation of the heat exchange of the marine tankers’ tubular heater made it possible to receive criterion equations for calculating average and local heat emission in free convection for a wide range of Ra and Pr numbers taking into account the variable viscosity. The oscillations intensify the heat exchange process. The heat exchange process of tubular heater while tankers are tossing belongs to a stationary mixed convection. Three zones of oscillation influence on the heat exchange of the horizontal cylinder are formed, and the boundaries of these zones are determined. The criterion equation, which generalizes the heat exchange at vibration, oscillations, rotation and horizontal cylinder flow, is received.

Keywords: heat exchange, variable viscosity, oscillations, horizontal cylinder, tossing, marine tankers.
