In this paper we consider an approach of changing the temperature of liquids and gases in a pipeline by local heating and cooling. The approach based on changing of temperature of series sections of the pipeline due to external modification of temper-ature of these sections. This situation could be used for heat sink or increasing of temperature. A model of heat transfer based on transfer of heat in a pipeline with account convection due to liquid/gas transport has been introduced. We also introduce an ana-lytical approach for analysis of liquid/gas transport with account transport of heat due to convection. The approach gives a possi-bility to take into account spatial and temporal variation of parameters of transport and at the same time to take into account non-linearity of considered processes.
