In this study, the separation of Neon stable isotopes in a transient square cascade has been simulated. The transient state equations for the square cascade were derived and discretized using the Crank–Nicolson solution method. The simulations showed that isotopes have an optimum value in the product flow at a specific time (optimum separation time), which is effective in the cost of isotope separation. The results indicated that by increasing the isotope mole fraction of Neon-20 in the feed from 0.05 to 0.7, the time to reach the maximum concentration of this isotope in the product (optimum time) increases by 2.7 times. In the case of heavy isotope (Neon-22), the concentration trend is the opposite of the Neon-20. Also, results showed that as the unit separation factor increases, the optimum times at low concentrations of light isotope (and high concentrations of heavy isotope) decreases.
