Computational Fluid Dynamic Modeling Of Natural Convection In Vertically Heated Rods, Mahesh Surendran
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Natural convection is a phenomenon that occurs in a wide range of applications such as cooling towers, air conditioners, and power plants. Natural convection may be used in decay heat removal systems such as spent fuel casks, where the higher reliability inherent of natural convection is more desirable than forced convection. Passive systems, such as natural convection, may provide better safety, and hence have received much attention recently. Cooling of spent fuel rods is conventionally done using water as the coolant. However, it involves contaminating the water with radiation from the fuel rods. Contamination becomes dangerous and difficult for humans …
Development Of A Three-Dimensional High-Order Strand-Grids Approach, Oisin Tong
Development Of A Three-Dimensional High-Order Strand-Grids Approach, Oisin Tong
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The strand-Cartesian grid approach is a unique method of generating and computing fluid dynamic simulations. The strand-Cartesian approach provides highly desirable qualities of fully-automatic grid generation and high accuracy. This work focuses on development of a high-accuracy methodology (high-order scheme) on strand grids for two and three dimensions.
In this work, the high-order scheme is extended to high-Reynolds number computations in both two and three dimensions with the Spalart-Allmaras turbulence model and the Menter SST turbulence model. In addition, a simple limiter is explored to allow the high-order scheme to accurately predict discontinuous flows.
Extensive verification and validation is conducted …
