A thermo-fluid-dynamic model for Stirling Engine Cycle simulation, first proposed by Rispoli in 1986, has been modified to keep into account the effect of gas axial turbulent conductivity and the results of recent research in oscillating flow friction and turbulent transition phenomena. Sudden cross sectional area changes are handled as flow discontinuities described by a set of equations solved by means of the secant method. Model prediction accuracy has been tested comparing numerical results with experimental data for the cogenerative unit V160. The comparison between numerical and experimental data shows model`s capability to take into account physical phenomena involved in working fluid evolution.
