Multi-phase flow and heat transfer; advanced reactor design; reactor thermal-hydraulics and safety. My current research is focused in four areas.
The offshore floating nuclear power plant
We are developing an offshore floating nuclear power plant concept that achieves unprecedented levels of safety. It does so through innovative design features that ensure indefinite cooling of the nuclear fuel (thus reducing the likelihood of accidents with fuel damage and radionuclide release), and eliminate the need for land evacuation, should such an accident actually occur. Both features are responsive to the new safety imperatives of a post-Fukushima world. This is a plant that can be entirely built (and decommissioned) as a floating rig in a shipyard, floated to the operating site (within 8–15 km of the coast), anchored in relatively deep water (i.e., ~100 m), and connected to the grid via an underwater transmission line. The economic potential is high, owing to efficient shipyard construction and decommissioning, and elimination of concrete structures from the plant design.

Fundamentals of Boiling
Cutting edge experimental techniques are used to study the physics of two-phase flow and heat transfer phenomena, in particular nucleate boiling, Critical Heat Flux (CHF) and quenching heat transfer. The group has optimized the use of synchronized infra-red thermography, high-speed video and Particle Image Velocimetry (PIV) to obtain detailed data for temperature distribution on the boiling surface, bubble departure diameter and frequency, growth and wait times, nucleation site density, near-wall void fraction, etc.. These data can be used to inform and validate models of boiling heat transfer, CHF and quenching, including multi-phase Computational Fluid Dynamics (CFD), and specifically Interface Tracking Methods (ITM). With such methods the geometry of the vapor-liquid interface is not assumed (e.g., bullet-shaped bubbles), but actually calculated from ‘first principles’.
Surface effects on boiling heat transfer
It is well known that boiling and quenching heat transfer depends strongly on the morphology and composition of the solid surface through which the heat transfer occurs. The relevant surface features are roughness, wettability (hydrophilicity), porosity, presence of cavities, size and shape of cavities, and thermo-physical properties of the surface material. My work has been exploring the separate effects of surface roughness, wettability and porosity on both Critical Heat Flux (CHF) and quenching heat transfer (Leidenfrost point temperature). This is made possible by the use of surfaces with engineered features (e.g. posts, coatings, nanoparticle layers) at the micro- and nano-scale, which enabled varying the surface roughness, wettability and porosity precisely and independently from each other. In fabricating the test surfaces, I work with Profs. Michael Rubner and Robert Cohen in DMSE and ChemE, respectively.
Nanofluids for Nuclear Applications
By seeding the nuclear reactor coolant with nanoparticles it is possible to enhance the rate at which energy is removed from the nuclear fuel under normal and accident conditions, thus improving the reactor’s economic and safety performance. The resulting particle-fluid system is called a ‘nanofluid’. We study the synthesis and behavior of nanofluids, including fundamentals of heat transfer, boiling phenomena and specifically the enhancement mechanisms for Critical Heat Flux (CHF) and quenching acceleration, which are relevant to the reactor application.
