A comprehensive numerical procedure for solving the Taylor-Melcher leaky dielectric model with charge evaporation
Electrosprays in the pure-ion mode are of particular interest to space propulsion because of its ability to produce high specific impulse and efficient electrical-to-kinetic energy transformation, together with its simplicity and compactness. Unlike electrospray emitters operating in the droplet …

Numerical simulation of a single emitter colloid thruster in pure droplet cone-jet mode
… tool to compute single-emitter current, droplet size, velocity, electric field strengths for a given geometry, fluid, flow rate, and voltage. We have approached this issue from the numerical perspective by developing a simulation of a colloid thruster operating in the single cone-jet pure …

An investigation of droplets and films falling over horizontal tubes
… and in particular, the behavior and role of droplets in horizontal-tube banks. Only axisymmetric cases, such as the formation of droplets from capillaries and jets, are generally considered in the literature. Flow visualization experiments were conducted on two horizontal-tube banks with …

Fabrication and robustness testing of superhydrophobic nanostructured surfaces for enhanced jumping condensation
… nano-structured surfaces which promote a jumping droplet mode of condensation have been shown to enhance heat transfer over conventional film wise condensation surfaces, but limited robustness testing has been reported validating feasibility of industrial implementation. This thesis seeks to …

Development and validation of a thermodynamic model for predicting mode transitions in falling film flows over horizontal tubes
… inter-tube space, the flow can take three main modes, namely: droplet, jet, and sheet modes. The accurate prediction of the prevailing flow mode is very important for the design and operation of these heat and mass exchangers, because the main performance characteristics (e.g. transport …
