<p>The results of a study examining the effect of nonuniform supply of equilibrium-dissociating nitrogen tetroxide into a pipe on its flow structure and heat transfer in it are presented. It is established that turbulization of such a coolant during its nonuniform supply into the pipe leads to intensification of heat transfer and to an increase in the Nusselt number throughout the entire flow region. It is shown that to intensify heat transfer in short pipes, it is advisable to increase the velocity of the inner axial flow compared to the outer annular flow, and that for long pipes, it is advisable to increase the velocity of the outer flow compared to the inner one.</p>

摘要

The results of a study examining the effect of nonuniform supply of equilibrium-dissociating nitrogen tetroxide into a pipe on its flow structure and heat transfer in it are presented. It is established that turbulization of such a coolant during its nonuniform supply into the pipe leads to intensification of heat transfer and to an increase in the Nusselt number throughout the entire flow region. It is shown that to intensify heat transfer in short pipes, it is advisable to increase the velocity of the inner axial flow compared to the outer annular flow, and that for long pipes, it is advisable to increase the velocity of the outer flow compared to the inner one.
