Numerical investigation on three-dimensional flow-field characteristics of propeller slipstream

摘要

摘要: 对不同前进比下的螺旋桨滑流流场进行了三维数值模拟,并采用诱导系数来量化螺旋桨的滑流效应,结合涡流理论深入分析和研究了单独螺旋桨的滑流流场特性。结果表明：螺旋桨滑流具有加速效应和扭转效应,其分别可用轴向诱导系数和环向诱导系数来量化；滑流的加速效应沿径向呈先增后减的趋势,而扭转效应沿径向递减；滑流的加速效应和扭转效应均随前进比的增加而减弱。螺旋桨的涡系结构主要包括绕桨叶的附着涡、从桨尖和桨根逸出的自由涡、从桨叶尾缘逸出的自由涡系,以及固体壁面附面层处的涡结构。螺旋桨滑流区的流场可由轴向诱导系数、环向平均的环向诱导系数以及涡系结构共同描述。

Abstract: The flow-field characteristics of propeller slipstream under different advance-diameter ratios were carried out by three-dimensional numerical simulation. The induced coefficient was used to quantify the slipstream effect; the slipstream characteristics were deeply explored on the basis of the vortex theory. Result showed that the accelerated effect of the slipstream increased firstly, and then decreased along the radial direction, while the twisted effect of the slipstream decreased along the radial direction; both the accelerated effect and the twisted effect decreased with the increment of the advance-diameter ratio; the flow-field of the propeller slipstream can be well described by the axial induced coefficient and circumferential induced coefficient with circumferentially averaged treatment as well as the vortex system structure.
