METHOD FOR DETERMINATION OF COMPATIBILITY OF COOLING FLUIDS Russian patent published in 1996 - IPC

FIELD: petroleum processing industry. SUBSTANCE: method involves heating tested fluids and their mix in presence of plates from metal alloy, which is present in cooling system of engine. After heating samples are cooled and refraction index is determined. Compatibility of fluids is judged by the following equation n_см≅ a•n₁+б•n₂,, where n_cm is refraction index of mix, n₁ are values of refraction index for tested fluids, n₂ are ratio by volume of samples of fluids. EFFECT: increased functional capabilities. 4 dwg, 1 tbl
