【摘要】：為了分析液黏傳動在純油膜剪切階段下摩擦副間隙內(nèi)流體傳熱特性對流場特性的影響,以一對雙圓弧油槽摩擦副間隙內(nèi)流場為研究對象,建立絕熱邊界條件下流場特性的簡化數(shù)學(xué)模型,對工作液黏溫特性進行實驗測定。通過考慮油液的黏溫特性,利用ANSYS CFX軟件對流場進行數(shù)值模擬,獲得不同工況條件下流場的流速特性、溫度特性以及壓力特性。研究表明:流體流速沿徑向總體整體呈遞增趨勢,流體流線軌跡整體成拋物線。流場溫度在沿徑向方向整體呈遞增趨勢,流場的溫升幅度隨轉(zhuǎn)速差增大而增大,隨入口流量增大而降低。流場壓力沿徑向近似線性遞減,流場壓差隨流場入口流量增大而增大,而摩擦副轉(zhuǎn)速差對流場壓差影響較小。
[Abstract]:In order to analyze the influence of fluid heat transfer characteristics on the flow field of a pair of friction pairs in the pure oil film shear stage, the flow field in a pair of double circular arc oil grooves is studied. A simplified mathematical model of flow field characteristics under adiabatic boundary conditions was established, and the viscosity and temperature characteristics of the working fluid were measured experimentally. The viscosity and temperature characteristics of the oil were taken into account. The flow field was simulated by ANSYS CFX software, and the velocity characteristics of the flow field under different working conditions were obtained. Temperature and pressure characteristics. The results show that the flow velocity increases gradually along the whole radial direction, the flow line trajectory becomes a parabola, and the temperature of the flow field increases along the radial direction. The temperature rise of the flow field increases with the increase of the velocity difference and decreases with the increase of the inlet flow rate. The pressure of the flow field decreases approximately linearly along the radial direction, and the pressure difference of the flow field increases with the increase of the inlet flow rate of the flow field. However, the friction pair speed difference has little effect on the pressure difference of the flow field.
