The performance optimization of a reverse flow combustor in a mini-jet engine is studied numerically. Different turbulence models (with appropriate mesh resolutions), i.e. steady (RANS) and unsteady k-ε (URANS) and the Reynolds stress model is adopted to investigate and compare the performance of the combustor. The probability density function (PDF) model is used to include combustion to complete...
This study extended the job demands-resources model by investigating the different impact of challenge and hindrance stressors on vigor (key dimension of work engagement) and exhaustion (key dimension of job burnout). Data was collected from 199 nurses of a hospital in a two-time-period survey with a three-month time lag. Results supported those theoretical extensions that the relationship between...
