Article
Sorption and desorption with hygroscopic hydrogels hold significant promise for thermal management, passive cooling, thermal energy storage, and atmospheric water harvesting. However, a comprehensive understanding of the energy and mass transport mechanisms in hygroscopic hydrogels remains missing, impeding accurate modeling and optimization. In th...

Boiling is an effective energy transfer process with substantial utility in energy applications. Boiling performance is described mainly by the heat transfer coefficient (HTC) and critical heat flux (CHF). Recent efforts for the simultaneous enhancement of HTC and CHF have been limited by an intrinsic trade‐off between them — HTC enhancement requir...

Article
Boiling heat transfer is dictated by interfacial phenomena at the three-phase contact line where vapor bubbles form on the surface. Structured surfaces have shown significant enhancement in critical heat flux (CHF) during pool boiling by tailoring interfacial phenomena. This CHF enhancement has been primarily explained by two structural effects: ro...
Thesis
Inverse opals have continuously attracted interest as a scalable, ordered porous material capable of enhancing energy, fluid, mass, or ion transport in a wide variety of applications. In particular, in heat transfer applications they have been used as porous coatings for condensers and boilers for increased efficiency in steam power plants and in t...

Evaporation plays a critical role in a range of technologies that power and sustain our society. Wicks are widely used as passive, capillary-fed evaporators, attracting much interest since these devices are highly efficient, compact, and thermally stable. While wick-based evaporators can be further improved with advanced materials and fabrication t...

Full-text available
Self-oscillatory and self-rotatory process driven by non-conservative forces have usually been treated as applications of the concepts of Hopf bifurcation and limit cycle in the theory of differential equations, or as instability problems in feedback control. Here we explore a complimentary approach, based on physical considerations of work extract...

Full-text available
The literature on dynamical systems has, for the most part, considered self-oscillators (i.e., systems capable of generating and maintaining a periodic motion at the expense of an external energy source with no corresponding periodicity) either as applications of the concepts of limit cycle and Hopf bifurcation in the theory of differential equatio...

By moving beyond a purely mathematical treatment of the solutions to the corresponding differential equations, and by incorporating energetic and thermodynamic criteria, we seek to arrive at a more general, flexible, and useful account of self-oscillatory phenomena in general, in both classical and quantum systems. These include, but are not limited to: heat and chemical engines, hydrodynamic instabilities, and Zel'dovich superradiance.
