Fuel pins assembled in Pressurized Water Reactor (PWR) and Liquid Metal-cooled Fast
Reactor (LMFR) core are usually cooled by single-phase coolant such as water or liquid …

Electrodialysis (ED) is more robust than reverse osmosis in terms of scaling, purity, and
control, but its efficiency is dependent on concentration polarization. Concentration …

In this paper, the turbulent flow in rod bundles with spacer grid and mixing vanes in nuclear
reactor core was studied using spectral element method with large eddy simulation (LES) …

In nuclear fuel assembly mixing vanes are fabricated on the spacer grids to promote
diversion cross flow and turbulent mixing. In order to investigate the decay of diversion cross …

In order to achieve high-fidelity PIV measurement for cross flow in rod bundles, the
measurement approach with the two-dimensional (2D) PIV has been optimized …

Cross flow and lateral pressure drop downstream a split-type mixing vane spacer grid in a
5× 5 rod bundle were experimentally measured by particle image velocimetry (PIV) and …

Swirling flow induced by the twist vanes can enhance the heat transfer in the rod-bundle fuel
assembly. In order to investigate accuracy of the k-ε models in predicting the swirling flow in …

Axial and cross flow downstream a split-type mixing vane spacer grid in a 5× 5 rod bundle
are measured with particle image velocimetry (PIV) at sub-channel Reynolds number (Re …

Experimental study of coherent structures downstream of a spacer grid with different
inclination angles (20°, 25°, 30°) of split-type mixing vanes in a 5× 5 rod bundle was …

A new test facility is presented, enabling single-phase isothermal fluid mechanics
experiments to support nuclear reactor safety studies. The applied measurement technique …
