本文分析了热球体和圆柱体在水中运动时的阻力减小情况，并与冷体的运动作了比较。采用ANSYS CFX程序对水蒸汽两相流对阻力的影响进行了实验研究和数值模拟。研究的初步结果表明，由于蒸汽的存在，与冷体相比，热体的阻力充分减小。(C)2012爱思唯尔有限公司保留所有权利。
An article presents an analysis of the drag force reduction during the hot spherical and cylindrical body movement in the water in comparison with the movement of the cold bodies. Influence of two-phase water-vapor flow on the drag was investigated experimentally and numerically using the ANSYS CFX code. The preliminary results of the investigation showed a sufficient reduction of the drag force for the hot body in comparison to the cold body due to the vapor presence. (C) 2012 Elsevier Ltd.
