This study introduces a new family of volumetric flatness factors which give rigorous parametric description the phenomenon intermittency in fully developed turbulent flows. These quantities gather information about most "active" part velocity field at each scale $\ell$, and allows one to define dimension function $p \to D_p$ that recovers correction structure exponents $\zeta_p$ an explicit wa...

Abstract The fuel shape and flow path structure of the plate-type reactor are different from those conventional rod-bundle reactor, which leads to difference between thermal-hydraulic phenomenon thermal conduction in rod bundle assembly. Therefore, this thesis, subchannel analysis model code applied developed. calculation results compared with simulation FLUENT MATRA experimental heat transfer ...
