An Experimental Study of Formation of Circulation Patterns in Laminar Unsteady Driven Cavity Flows Using Particle Image Velocimeter (PIV) Techniques
… dynamics case often used for benchmarking of computational codes. Previous work has primarily focused on improving computational codes, experimental work is lacking and focused on obtaining steady state readings. The test cavity is 1 inch (25.4mm) high by 1 inch (25.4 mm) wide leading to an …

Quasi-static Methods in Neutron Transport
… been adopted and implemented for the design of computational codes capable of performing reliable transient calculations. The underlying idea has been the development of the kinetic module on top of the transport solver, in such a way that the former can be flexibly plugged into the codes ystem, …

3D Reactor Physics Modelling Of Reduced-Moderation Water Reactor (RMWR) Fuel
… current methods of modeling: 2D deterministic codes are not sufficient and 3D Monte Carlo codes are slow due to the need to generate data for a full core axially heterogeneous RMWR model. These drawbacks severely limit the modeling capability of the RMWR. The objective is to observe the …
