Optimization-based investigations of a two-phase thermofluidic oscillator for low-grade heat conversion

Table 3 Asymptotic stability and performance of a NIFTE with nominal parameter values (Table 2), except L_f=4.74×10⁵ kg m⁻⁴ s⁻¹

The eigenvalues causing instability are shown in red. The period, exergetic efficiency, power output and thermal input of the cyclic steady states are also reported for comparison. CSS1: stable limit cycle of NTP model. CSS2 unstable limit cycle of NTP model. CSS1’: (unique) stable limit cycle of NTP-TL model. The origin is an unstable equilibrium point of both NTP and NTP-TL models
