Through the Oak Ridge Institute for Science and Education (ORISE) this posting seeks a qualified candidate to participate with NETL researchers on a project developing a potassium-seeding method for increasing the conductivity of oxy-kerosene combustion products. The augmented combustion products are used in experiments regarding direct power-extraction from a flowing plasma via interaction with a magnetic field (a magnetohydrodynamic interaction). Emulsions of K2CO3 brine and kerosene have proven effective, but an increased concentration of K2CO3 in the brine is desired. Stable fuel emulsions with high-concentration brines are difficult to generate.
This project would explore emulsion-generation methods with potassium carbonate (K2CO3) brines from 20 mass-percent to fully saturated. Results will include diameter measurements of the dispersed-phase droplets, time the emulsion remains fully mixed, viscosity, predicted droplet size when the emulsion passes through a crossflow atomizer.
The selected applicant will gain hands on experience with and an enhanced knowledge of computational fluid-dynamics (CFD) modeling of gas-driven atomization - non-Newtonian fluids, measurement of liquid characteristics (viscosity, surface tension), and chemical interactions between ionic and anionic surfactants with brine.
Ideal candidates preferred skills include:
1. CFD Modeling
2. Liquid characteristic measuring techniques (e.g.viscometry, sessile-drop, pH) with statistically significant results
3. Design Of Experiment
