The heat released from the flat surface is cooled by the use of jet impingement technique. The heat flux from the isothermally heated flat surface due to two-dimensional turbulent twin oblique confined slot-jet impingement is studied numerically using the ANSYS FLUENT software. Initially the flow and thermal fields for a normal confined slot-jet impingement are investigated using the RNG k-ε model and the SST k- ω model. The local Nusselt number distribution predicted by the SST k-ω model agrees notably better with the existing experimental data. Subsequently, the SST k-ω is employed to study the twin oblique impinging jet heat transfer problem. The study is conducted by varying the jet exit Reynold number, the jet to jet separation distance, jet -exit to target plate distance and the inclination angle of the jet to the impingement. Results indicate that impingement angle is reduced from 90o, the peak Nusselt number at the impingement surface is gradually reduced and its location slightly shifts away from the axis with slight decrease of the average Nusselt number for any combination of Re, L, H. The average Nusselt number is a direct function of the Reynold number and the impingement angle and is inverse function of the jet to target plate separation distance.
