    (Springer, 2012-05) Uysal, Alper; Korgavus, Ayhan; Korgavus, Orhan; Özalp, A. Alper; Uludağ Üniversitesi/Mühendislik Fakültesi/Makine Mühendisliği Bölümü.; 0000-0002-4976-9027; ABI-6888-2020; 6506131689
    This paper presents a numerical investigation on the momentum and thermal characteristics of an intercooler connection hose that is in use in the 1.3 SDE 75 CV type FIAT engine. Computational analyses are carried out with ANSYS FLUENT v.12.0.1, where both stationary and vibrating scenarios are handled. The work is structured in accordance with the "Subsystem Functional Description for Charge Air Hoses Fiat 225 Euro 5" FIAT standard, where the air mass flow rate, temperature, and gage pressure at the hose inlet are identified as = 0.085 kg/s, (in) = 90A degrees C, and (in) = 130 kPa, respectively. In the stationary case, it is determined that the pressure loss value in the air domain of the hose is Delta (K) = 1.50 kPa; moreover, the corresponding data for the temperature drop is Delta = 0.80A degrees C. Vibration is characterized by employing simple harmonic motion at the engine side of the hose. The fluid-solid interaction methodology showed that pressure loss values grow due to vibration; moreover, the impact of vibration came out to generate diverse fluctuation schemes at different sections of the hose.
