Оptimization of calculation and selection of heat exchange equipment in the use of nanofluid heat carriers

Abstract

In modern chemical, food, pharmaceutical, technologies an important place is occupied by heat exchange processes, which account for the dominant share of all energy consumption of enterprises. The efficiency of these processes largely depends on the correct choice of heat exchange equipment. Very often the heat exchange equipment is selected for maximum power and then throughout the period of its operation works with the overuse of thermal energy, which places a heavy burden on the work of the whole enterprise and entire industries as ahole. Therefore, the choice of high-efficiency thermal equipment must also be accompanied by aorrect preliminary calculation of its heat output. To date, an important part of the energy saving of heat exchange equipment is the use of modern nanofluids coolants. However, the choice and calculation of heat exchangers with nanofluids encounters problems of correct theoretical calculation, because numerical empirical equations that describe the processes of heat exchange with classical coolants do not accurately reflect the process using nanofluids. Additional costly experiments are needed to make corrections to existing classical equations that are losing their universality.
