Witryna13 gru 2024 · Abstract The paper presents the results of numerical simulation of complex shock-wave structures arising from an under-expanded jets impingement on an inclined flat plate. The plate deflection angles equal to 45°, 60°, and 90° are investigated, which corresponds to different types of shock waves interference. Witryna1 gru 2024 · In the present work, inclined air jets impinging on heated absorber plate have been applied for the heat transfer enhancement. Impingement of air jet at various angles on heated plate would generate an elevated turbulence in the region of fluid that helps in enhancing the coefficient of heat transfer. WitrynaA jet, inclined in traverse direction, improves hydrodemolition processes. The gain in efficiency is up to 8% at an angle of 30° which would be the optimum angle. If, however, the jet is directed against the traverse direction, efficiency drops. This drop (down to 25%) is much more intense than the gain in efficiency. danoneawayfromhome.com
