Abstract The authors performed an experimental study of the effects of non-isothermal and unsteady hydrodynamic conditions on generation and evolution of turbulence. Measurements of the instantaneous axial and radial velocities and temperature in unsteady conditions, calculation of their average and pulsation magnitude, and their correlation were carried out. A physical model of the hydrodynamic unsteady turbulent flow was formulated based on the analysis of the frequency spectra of pulse parameters.
