In this work, the utility of surfaces featuring phase change materials (PCMs) encapsulated within micro-reservoirs was evaluated as a passive thermal management system for mitigation of transient temperature spikes.
Moreover, the main control is deployed in dqo reference frame, which guarantees zero steady-state error, fast transient response during system disturbances and mitigation of harmonics when nonlinear loads are present.
Resulting degradation effects of the fuel cell and their influence on transient operation behavior are as well introduced as mitigation strategies by means of optimized operating conditions and fuel cell system architecture.
The transients chosen for evaluation of the efficiency of mitigation measures were the unprotected loss-of-flow (ULOF), the unprotected loss-of-heat-sink (ULOHS) and the unprotected transient-overpower (UTOP).
Lee and Campbell presented a hotspot mitigation protocol (HMP) [8], where hotspots represent transient but highly congested regions.
This paper presents the simulation and transient analysis of conventional and advanced aircraft electric power systems with harmonics mitigation.
Simulated ULOF transients do not lead to energetic power excursions thanks to the mitigation provisions and to the core design.
As a consequence of our findings, common transient measurements of the ORR activity might not be sufficient to investigate suitable mitigation strategies for the ORR inhibition in phosphoric acid electrolyte.
First, the mitigation should be carried out until the maximum fuel temperature reaches under transient.
These experimental results emphasize the importance of evaluating the potential tradeoffs of liquefaction mitigation, which may reduce settlement and sometimes tilt, but result in larger transient drifts and damage to the superstructure.
