Notes:
This study was numerically and experimentally investigated on improvement capturevelocity for increasing inhalation efficiency of hood in local ventilation system. The inhalationefficiency of hood was studied to improve by increasing inhalation force of the hood that attached thenew device named “Gas-Guide-Device (GGD)”. Also, harmful material that couldn’t inhale in hoodwas removed by increasing capture velocity at the edge of hood. For the numerical study,computational fluid dynamic (CFD) was used to predict the improvement of flow velocity withattached GGD in hood. To verify the numerical result, the flow velocity was experimentally measuredusing a hot-wire type anemometer. As a result of the numerical and experimental study for improvingthe effect of the GGD on the inhalation efficiency of the hood, it was verified that the capture velocityaround the hood inlet was relatively higher for the hood with the GGD than for the one without it
