Investigation of effect of depressant additives on hydraulic resistance and heat exchange in oil mixture flow Original Research Article

The results of investigation of the laws of hydrodynamic resistance and heat exchange by the data of experimental-industrial tests of depressant additives and heat hydraulic calculation of the linear Kumkol–Karakoin section of the Kumkol–Chymkent main pipeline are presented. The empirical relations for hydrodynamic resistance and heat exchange coefficients of turbulent oil-mixture pipe flow with additives are established in consequence of generalization of the test data.
