초록

In this numerical study, the effect of baffle orientation and baffle size on the shell-side pressure drop in a liquefied natural gas (LNG) vaporizer was investigated. The shell side of the LNG vaporizer with vertical, horizontal and rotated baffle orientations and baffle cuts of 30%, 40% and 50% has been solved by ANSYS CFX 16.2. The results showed that the horizontal baffle orientation demonstrated a lower pressure drop compared to the vertical and rotated baffle orientations, and the 50% baffle cut had a lower pressure drop compared to that in the other two baffle cuts in all baffle orientations. The results also showed that the dependency of the pressure drop on the Reynolds number appeared to decrease for all baffle orientations when baffle cuts increased from 30% to 50%.
