Короткий опис(реферат):
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.
