The aim of the paper is to compare the changes in dynamics of a free plasma flow consequent upon inherence of a wall barrier, considering different flow rates and different energy inputs. The determination of the velocity of macroscopic structures in a free plasma flow is achieved using both the correlation analysis and the testing procedures based on differential geometry. The obtained results indicate that the self-organization of the vortex structure is prompted by quasi-periodic changes of the anisotropy of heat distribution, given by the product of the enthalpy and velocity of the plasma flow
