Numerical Studies on Fluid Flow and Heat Transfer in the Shell Side of Reticulation Orifice-baffle Longitudinal Flow Type Heat Exchanger
网状孔板纵向流换热器壳程流体流动及换热特性的数值模拟

Numerical simulation of fluid flow and heat transfer in the shell side of reticulation orifice-baffle longitudinal flow type heat exchanger is carried out with CFD software.Heat transfer enhancement principle of the reticulation orifice-baffle is summarized,and the influences of space between baffles(L),and open area ratio(y) on its heat transfer and pressure drop Dp analyzed,and correlations are developed for the models.The results indicate that jet flow and second flow appear after fluid leaves the reticu...
