The effect of the tilt angle of an orifice plate on the bubble volume was investigated by using the same orifice plates used in part 1, which dealt with the bubble formation from a horizontally placed orifice plate. Because of the tilt of an orifice plate, the buoyancy of a developing bubble has a force component which drifts the bubble on the surface of plate. This drifting force component, which is given by a function of the tilt angle, is the major difference from the horizontal plate (the tilt angle is zero). The bubble drifting force component influences the bubble detachment mechanism most. The effect of the tilt angle on the bubble volume is dependent on the tilt angle and also the contact angle of water on an orifice plate. In the case of wettable surface (low contact angle), the bubble size decreases with the increasing tilt angle. In the case of a moderately hydrophobic surface, the increase of bubble volume followed by a decrease as a function of the tilt angle was observed. With highly hydrophobic surface at higher tilt angles, bubbles develop into sliding bubbles which do not detach from the orifice plate at the location of the orifice. Mechanisms of bubble formation and of bubble detachment are discussed in light of the bubble drifting force component which can be described as a function of the tilt angle of an orifice plate.
