HYDRAULIC RESISTANCE AND HEAT TRANSFER IN NON-ISOTHERMAL PIPELINES, TRANSPORTING NON-NEWTONIAN OILS USING DRAG REDUCING ADDITIVES

Abstract

Background Forecasting hydraulic resistance of non-isothermic turbulent flows of non-Newtonian fluids is of great industrial importance. There are practically no studies in the literature on calculating hydraulic resistance reduction using polymer additives for turbulent flows of thermally dependent non-Newtonian fluids. Aims and Objectives Calculation of hydraulic resistance and heat transfer of turbulent flows of non-Newtonian fluids in non-isothermal oil pipelines using polymeric additives. Methods Mathematical modeling and numerical calculations for determining the hydraulic resistance coefficient in non-isothermal oil pipelines transporting non-Newtonian power-law oil with parameters depending on the temperature of using drag reducing additives. Results A mathematical model has been developed for a non-isothermal oil pipeline transporting non-Newtonian power-law oil, with parameters depending on temperature using drag reducing additives.
