Abstract:
In this article are described a non-isothermal current of high-viscosity oil. A non-isothermal
current of viscous liquid on the trunk pipeline it is characteristic of transportation of oil and oil products with preliminary heating from places of production to a customer, of a current of hot water from combined heat and power plant to inhabited arrays and production locations, etc. The
one-dimensional mathematical model of a non-isothermal current of viscous liquid and a formula of
cost fuel – power expenses for the stationary mode of a current are examined. It is spoken in
detail the process of calculation of optimum speed of a current for transportation of
high-viscosity oil and oil products in the warmed-up state on pipelines at
which the total cost of energy costs of pumping and heating of oil would be minimum.
