Study of the hydrodynamic cycle of technical reactors by the use of a radioactive indicator

Conclusion The quantities defining the intensity of internal mixing in reactors with a volume of 76 and 186 liters (filled and empty) are determined by the method of introducing radioactive carbon dioxide C¹⁴O₂ as a tracer.It is shown that in the filled reactor when Re=12, the quantity Pe_L is close to the limiting value, equal to 2; the cycle in this reactor corresponds to ideal displacement.Change of temperature has no effect on mixing in the filled reactor.It is shown that in the empty reactor, when Re changes from 60 to 177 the parameter Pe_L remains almost constant and equal to 0.6. In this case, ideal displacement is not achieved in the empty reactors over the range of Re numbers investigated.Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 11, pp. 44–46, November, 1972.
