Predicted effect of Rf and Lf on NIFTE performance using the NTP-TL model. A unique, stable cyclic steady state is detected here. The effect on both the exegetic efficiency ηex (left plots) and the average power output \(\dot {W}_{\mathrm {l}}\) (right plots) is shown for each cyclic steady state. \(R_{\mathrm {f}}^{+}\) and \(L_{\mathrm {f}}^{+}\) refer to Rf and Lf normalized by their respective nominal values in Table 2. The remaining parameters are set to their nominal values. All of the limit cycles are stable on both plots
