Abstract (2. Language): 
The present study deals with the flow and heat transfer characteristics of inclined, as opposed to perpendicular or normal, impinging jets. Extensive visualization experiments are conducted and a digital camera analyzed the flow. In order to further understand the effect of the inclination of impinging jets, the heat transfer distributions along a target plate are also measured. From the results taken, Nusselt number is calculated and compared to the case of inclined single impinging jets. Furthermore, a comparison between a single jet and twin-jet inclined to face each other was made, and how the heat transfer characteristics are affected by the jet inclination is presented. The heat transfer experiments are conducted under Reynolds number 5.0  103, and the normalized nozzle-to-plate spacing H/Dh (H: nozzle-to-plate spacing, Dh: the hydraulic diameter of the slot nozzle) ranging from 3 to 7, and the jet inclination ranging from =0~60°, giving valuable information regarding the changes that occur due to the inclined impinging jets.
