Abstract

The article presents the results of an experimental study of friction and heat transfer in a cylindrical tube. The results of the experiment showed that a sharp increase in the temperature of the gas stream contributes to the formation of thermal and hydrodynamic instability, which in combination with non-isothermal conditions create conditions that lead to a decrease in the efficiency of heat transfer. This process is facilitated by the dynamics of the process of increasing the temperature of the flow, starting from the threshold of 3000 K/c and more
