Validation of ion and electron scale gyrokinetic simulations in an NSTX H-mode and comparisons with a synthetic diagnostic for high-k scattering ?

Ruiz Ruiz, Juan,Ph. D.Massachusetts Institute of Technology. (Massachusetts Institute of Technology, 2019)

In this thesis I perform an extensive validation study in an NSTX NBI-heated H-mode discharge, predicting that electron thermal transport can be entirely explained by shortwavelength electron-scale turbulence fluctuations ...
Prediction of departure from nucleate boiling in subchannel applications : from mechanistic modeling to hybrid framework ?

Zhao, Xingang,Ph.D.Massachusetts Institute of Technology. (Massachusetts Institute of Technology, 2019)

The critical heat flux (CHF) corresponding to the departure from nucleate boiling (DNB) is a regulatory limit for licensing of pressurized water reactors (PWRs). Under DNB conditions, the heated surface is blanketed by a ...
Measurements of divertor target plate conditions and their relationship to scrape-off layer transport ?

Kuang, Adam QingYang. (Massachusetts Institute of Technology, 2019)

Cross-field filamentary transport in the scrape-off layer (SOL) is important for controlling SOL profiles, main-chamber recycling fluxes, and divertor operation. However, questions remain about the extent to which divertor ...
