A Twin-fluid atomizer of the film impingement type exhibits a good performance in spray characteristics. For application to the twin-fluid atomizer, we propose a new film generation method which is greatly liquid-jet-impingement-on-the-wall type. In this type of atomizer, the liquid film thickness influences the spray characteristics. In this report, the thickness distributions of liquid films formed by obliquely impinging jet on the wall have been calculated and compared to the measurements. According to the calculation, as the Reynolds number of the liquid jet increases, the film thickness decreases. The greater the distance between the stagnation point on the wall and the measuring point, the more uniform the film thickness becomes. The calculations of film thickness are slightly thinner than measurements. But the calculations of thickness distribution are qualitatively coincident with measurements.
