ملخص

A framework to analyze the fluid mechanisms in baffle type degassers is presented and particularly applied to an innovative airfoil-type degasser. Major fluid events in conventional baffle type degassers such as bubbles rising inside the oil layer and the flow of the oil layer itself were taken into account. However, in the current airfoil-type degasser oil flows over an airfoil surface and at the same time is exposed to an air jet. This air jet attaches to the airfoil surface due to the so called Coanda effect as observed in some trial runs of the system. A curved strip model is suggested to estimate the pressure reduction due to the jet curvature. Then we have performed a convective mass transfer analysis in order to determine the jet effect in reducing the partial pressure of the gas on the oil surface and increasing the rate of bubble formation.
